amo 1:1GOD'S JUDGMENTS ON SYRIA, PHILISTIA, TYRE, EDOM, AND AMMON. (Amo 1:1-15)
The words of Amos--that is, Amos' oracular communications. A heading found only in Jer 1:1.
among the herdmen--rather, "shepherds"; both owning and tending sheep; from an Arabic root, "to mark with pricks," namely, to select the best among a species of sheep and goats ill-shapen and short-footed (as others explain the name from an Arabic root), but distinguished by their wool [MAURER]. God chooses "the weak things of the world to confound the mighty," and makes a humble shepherd reprove the arrogance of Israel and her king arising from prosperity (compare Sa1 17:40).
which he saw--in supernatural vision (Isa 1:1).
two years before the earthquake--mentioned in Zac 14:5. The earthquake occurred in Uzziah's reign, at the time of his being stricken with leprosy for usurping the priest's functions [JOSEPHUS, Antiquities, 9:10.4]. This clause must have been inserted by Ezra and the compilers of the Jewish canon.
amo 1:2will roar--as a lion (Joe 3:16). Whereas Jehovah is there represented roaring in Israel's behalf, here He roars against her (compare Psa 18:13; Jer 25:30).
from Zion . . . Jerusalem--the seat of the theocracy, from which ye have revolted; not from Dan and Beth-el, the seat of your idolatrous worship of the calves.
habitations . . . mourn--poetical personification. Their inhabitants shall mourn, imparting a sadness to the very habitations.
Carmel--the mountain promontory north of Israel, in Asher, abounding in rich pastures, olives, and vines. The name is the symbol of fertility. When Carmel itself "withers," how utter the desolation! (Sol 7:5; Isa 33:9; Isa 35:2; Jer 50:19; Nah 1:4).
amo 1:3Here begins a series of threatenings of vengeance against six other states, followed by one against Judah, and ending with one against Israel, with whom the rest of the prophecy is occupied. The eight predictions are in symmetrical stanzas, each prefaced by "Thus saith the Lord." Beginning with the sin of others, which Israel would be ready enough to recognize, he proceeds to bring home to Israel her own guilt. Israel must not think hereafter, because she sees others visited similarly to herself, that such judgments are matters of chance; nay, they are divinely foreseen and foreordered, and are confirmations of the truth that God will not clear the guilty. If God spares not the nations that know not the truth, how much less Israel that sins wilfully (Luk 12:47-48; Jam 4:17)!
for three transgressions . . . and for four--If Damascus had only sinned once or twice, I would have spared them, but since, after having been so often pardoned, they still persevere so continually, I will no longer "turn away" their punishment. The Hebrew is simply, "I will not reverse it," namely, the sentence of punishment which follows; the negative expression implies more than it expresses; that is, "I will most surely execute it"; God's fulfilment of His threats being more awful than human language can express. "Three and four" imply sin multiplied on sin (compare Exo 20:5; Pro 30:15, Pro 30:18, Pro 30:21; "six and seven," Job 5:19; "once and twice," Job 33:14; "twice and thrice," Margin; "oftentimes," English Version, Job 33:29; "seven and also eight," Ecc 11:2). There may be also a reference to seven, the product of three and four added; seven expressing the full completion of the measure of their guilt (Lev 26:18, Lev 26:21, Lev 26:24; compare Mat 23:32).
threshed--the very term used of the Syrian king Hazael's oppression of Israel under Jehu and Jehoahaz (Kg2 10:32-33; Kg2 13:7). The victims were thrown before the threshing sledges, the teeth of which tore their bodies. So David to Ammon (Sa2 12:31; compare Isa 28:27).
amo 1:4Hazael . . . Ben-hadad--A black marble obelisk found in the central palace of Nimroud, and now in the British Museum, is inscribed with the names of Hazael and Ben-hadad of Syria, as well as Jehu of Israel, mentioned as tributaries of "Shalmanubar," king of Assyria. The kind of tribute from Jehu is mentioned: gold, pearls, precious oil, &c. [G. V. SMITH]. The Ben-hadad here is the son of Hazael (Kg2 13:3), not the Ben-hadad supplanted and slain by Hazael (Kg2 8:7, Kg2 8:15). The phrase, "I will send a fire," that is, the flame of war (Psa 78:63), occurs also in Amo 1:7, Amo 1:10, Amo 1:12, Amo 1:14, and Amo 2:2, Amo 2:5; Jer 49:27; Hos 8:14.
amo 1:5bar of Damascus--that is, the bar of its gates (compare Jer 51:30).
the inhabitant--singular for plural, "inhabitants." HENDERSON, because of the parallel, "him that holdeth the scepter," translates, "the ruler." But the parallelism is that of one clause complementing the other, "the inhabitant" or subject here answering to "him that holdeth the scepter" or ruler there, both ruler and subject alike being cut off.
Aven--the same as Oon or Un, a delightful valley, four hours' journey from Damascus, towards the desert. Proverbial in the East as a place of delight [JOSEPHUS ABASSUS]. It is here parallel to "Eden," which also means "pleasantness"; situated at Lebanon. As JOSEPHUS ABASSUS is a doubtful authority, perhaps the reference may be rather to the valley between Lebanon and Anti-Lebanon, called El-Bekaa, where are the ruins of the Baal-bek temple of the sun; so the Septuagint renders it On, the same name as the city in Egypt bears, dedicated to the sun-worship (Gen 41:45; Heliopolis, "the city of the sun," Eze 30:17, Margin). It is termed by Amos "the valley of Aven," or "vanity," from the worship of idols in it.
Kir--a region subject to Assyria (Isa 22:6) in Iberia, the same as that called now in Armenian Kur, lying by the river Cyrus which empties itself into the Caspian Sea. Tiglath-pileser fulfilled this prophecy when Ahaz applied for help to him against Rezin king of Syria, and the Assyrian king took Damascus, slew Rezin, and carried away its people captive to Kir.
amo 1:6Gaza--the southernmost of the five capitals of the five divisions of Philistia, and the key to Palestine on the south: hence put for the whole Philistine nation. Uzziah commenced the fulfilment of this prophecy (see Ch2 26:6).
because they carried away . . . the whole captivity--that is, they left none. Compare with the phrase here, Jer 13:19, "Judah . . . carried captive all of it . . . wholly carried away." Under Jehoram already the Philistines had carried away all the substance of the king of Judah, and his wives and his sons, "so that there was never a son left to him, save Jehoahaz"; and after Amos' time (if the reference includes the future, which to the prophet's eye is as if already done), under Ahaz (Ch2 28:18), they seized on all the cities and villages of the low country and south of Judah.
to deliver them up to Edom--Judah's bitterest foe; as slaves (Amo 1:9; compare Joe 3:1, Joe 3:3, Joe 3:6). GROTIUS refers it to the fact (Isa 16:4) that on Sennacherib's invasion of Judah, many fled for refuge to neighboring countries; the Philistines, instead of hospitably sheltering the refugees, sold them, as if captives in war, to their enemies, the Idumeans.
amo 1:7fire--that is, the flame of war (Num 21:28; Isa 26:11). Hezekiah fulfilled the prophecy, smiting the Philistines unto Gaza (Kg2 18:8). Foretold also by Isa 14:29, Isa 14:31.
amo 1:8Ashdod, &c.--Gath alone is not mentioned of the five chief Philistine cities. It had already been subdued by David; and it, as well as Ashdod, was taken by Uzziah (Ch2 26:6). Gath perhaps had lost its position as one of the five primary cities before Amos uttered this prophecy, whence arose his omission of it. So Zep 2:4-5. Compare Jer 47:4; Eze 25:16. Subsequently to the subjugation of the Philistines by Uzziah, and then by Hezekiah, they were reduced by Psammetichus of Egypt, Nebuchadnezzar, the Persians, Alexander, and lastly the Asmoneans.
amo 1:9Tyrus . . . delivered up the . . . captivity to Edom--the same charge as against the Philistines (Amo 1:6).
remembered not the brotherly covenant--the league of Hiram of Tyre with David and Solomon, the former supplying cedars for the building of the temple and king's house in return for oil and corn (Sa2 5:11; Kg1 5:2-6; Kg1 9:11-14, Kg1 9:27; Kg1 9:10-22; Ch1 14:1; Ch2 8:18; Ch2 9:10).
amo 1:10fire--(Compare Amo 1:4, Amo 1:7; Isa. 23:1-18; Eze. 26:1-28:26). Many parts of Tyre were burnt by fiery missiles of the Chaldeans under Nebuchadnezzar. Alexander of Macedon subsequently overthrew it.
amo 1:11Edom . . . did pursue his brother-- (Isa 34:5). The chief aggravation to Edom's violence against Israel was that they both came from the same parents, Isaac and Rebekah (compare Gen 25:24-26; Deu 23:7-8; Oba 1:10, Oba 1:12; Mal 1:2).
cast off all pity--literally, "destroy compassions," that is, did suppress all the natural feeling of pity for a brother in distress.
his wrath for ever--As Esau kept up his grudge against Jacob, for having twice supplanted him, namely, as to the birthright and the blessing (Gen 27:41), so Esau's posterity against Israel (Num 20:14, Num 20:21). Edom first showed his spite in not letting Israel pass through his borders when coming from the wilderness, but threatening to "come out against him with the sword"; next, when the Syrians attacked Jerusalem under Ahaz (compare Ch2 28:17, with Kg2 16:5); next, when Nebuchadnezzar assailed Jerusalem (Psa 137:7-8). In each case Edom chose the day of Israel's calamity for venting his grudge. This is the point of Edom's guilt dwelt on in Oba 1:10-13. God punishes the children, not for the sin of their fathers, but for their own filling up the measure of their fathers' guilt, as children generally follow in the steps of, and even exceed, their fathers' guilt (compare Exo 20:5).
amo 1:12Teman--a city of Edom, called from a grandson of Esau (Gen 36:11, Gen 36:15; Oba 1:8-9); situated five miles from Petra; south of the present Wady Musa. Its people were famed for wisdom (Jer 49:7).
Bozrah--a city of Edom (Isa 63:1). Selah or Petra is not mentioned, as it had been overthrown by Amaziah (Kg2 14:7).
amo 1:13Ammon--The Ammonites under Nahash attacked Jabesh-gilead and refused to accept the offer of the latter to save them, unless the Jabesh-gileadites would put out all their right eyes (Sa1 11:1, &c.). Saul rescued Jabesh-gilead. The Ammonites joined the Chaldeans in their invasion of Judea for the sake of plunder.
ripped up . . . women with-child--as Hazael of Syria also did (Kg2 8:12; compare Hos 13:16). Ammon's object in this cruel act was to leave Israel without "heir," so as to seize on Israel's inheritance (Jer 49:1).
amo 1:14Rabbah--the capital of Ammon: meaning "the Great." Distinct from Rabbah of Moab. Called Philadelphia, afterwards, from Ptolemy Philadelphus.
tempest--that is, with an onset swift, sudden, and resistless as a hurricane.
day of the whirlwind--parallel to "the day of battle"; therefore meaning "the day of the foe's tumultuous assault."
amo 1:15their king . . . princes--or else, "their Molech (the idol of Ammon) and his priests" [GROTIUS and Septuagint]. Isa 43:28 so uses "princes" for "priests." So Amo 5:26, "your Molech"; and Jer 49:3, Margin. English Version, however, is perhaps preferable both here and in Jer 49:3; see on Jer 49:3.
