A Commentary, Critical, Practical, and Explanatory on the Old and New Testaments, by Robert Jamieson, A.R. Fausset and David Brown  at sacred-texts.com
1 Chronicles 14:1
ch1 14:1HIRAM'S KINDNESS TO DAVID; DAVID'S FELICITY. (Ch1 14:1-2)
Now Hiram king of Tyre--[See on Sa2 5:11]. The alliance with this neighboring king, and the important advantages derived from it, were among the most fortunate circumstances in David's reign. The providence of God appeared concurrent with His promise in smoothing the early course of his reign. Having conquered the Jebusites and made Zion the royal residence, he had now, along with internal prosperity, established an advantageous treaty with a neighboring prince; and hence, in immediate connection with the mention of this friendly league, it is said, "David perceived that the Lord had confirmed him king over Israel."
1 Chronicles 14:2
ch1 14:2his kingdom was lifted up on high, because of his people Israel--This is an important truth, that sovereigns are invested with royal honor and authority, not for their own sakes so much as for that of their people. But while it is true of all kings, it was especially applicable to the monarchs of Israel, and even David was made to know that all his glory and greatness were given only to fit him, as the minister of God, to execute the divine purposes towards the chosen people.
1 Chronicles 14:3
ch1 14:3HIS WIVES. (Ch1 14:3-7)
David took more wives at Jerusalem--(See on Sa2 3:5). His concubines are mentioned (Ch1 3:9), where also is given a list of his children (Ch1 14:5-8), and those born in Jerusalem (Sa2 5:14-16). In that, however, the names of Eliphalet and Nogah do not occur, and Beeliada appears to be the same as Eliada.
1 Chronicles 14:8
ch1 14:8HIS VICTORIES OVER THE PHILISTINES. (Ch1 14:8-17)
all the Philistines went up to seek David--in the hope of accomplishing his ruin (for so the phrase is used, Sa1 23:15; Sa1 24:2-3) before his throne was consolidated. Their hostility arose, both from a belief that his patriotism would lead him, ere long, to wipe out the national dishonor at Gilboa, and by fear, that in any invasion of their country, his thorough knowledge of their weak points would give him superior advantages. They resolved, therefore, to surprise and crush him before he was fairly seated on his throne.
1 Chronicles 14:11
ch1 14:11they came up to Baal-perazim; and David smote them there--In an engagement fought at Mount Perazim (Isa 28:21), in the valley of Rephaim, a few miles west of Jerusalem, the Philistines were defeated and put to flight.
1 Chronicles 14:12
ch1 14:12when they had left their gods--(See on Sa2 5:21).
1 Chronicles 14:13
ch1 14:13the Philistines yet again spread themselves--They renewed the campaign the next season, taking the same route. David, according to divine directions, did not confront them.
1 Chronicles 14:14
ch1 14:14Go not up after them--The text in Sa2 5:23, more correctly has, "Go not up."
turn away from them--that is, by stealing round a baca-grove, come upon their rear.
1 Chronicles 14:15
ch1 14:15for God is gone forth before thee--"a sound of going in the tops of the mulberry trees," that is, the rustling of the leaves by a strong breeze suddenly rising, was the sign by which David was divinely apprised of the precise moment for the attack. The impetuosity of his onset was like the gush of a pent-up torrent, which sweeps away all in its course; and in allusion to this incident the place got its name.
1 Chronicles 14:16
ch1 14:16from Gibeon . . . to Gazer--Geba or Gibea (Sa2 5:25), now Yefa, in the province of Judah. The line from this to Gazer was intersected by the roads which led from Judah to the cities of the Philistines. To recover possession of it, therefore, as was effected by this decisive battle, was equivalent to setting free the whole mountain region of Judah as far as their most westerly slope [BERTHEAU].
