Psalms Chapter 75
Al-taschith--(See on Psa 57:1, title). In impending danger, the Psalmist, anticipating relief in view of God's righteous government, takes courage and renders praise. (Psa 75:1-10)
God's name or perfections are set forth by His wondrous works.
These verses express the purpose of God to administer a just government, and in a time of anarchy that He sustains the nation. Some apply the words to the Psalmist.
receive the congregation--literally, "take a set time" (Psa 102:13; Hos 2:3), or an assembly at a set time--that is, for judging.
pillars of it-- (Sa1 2:8).
Here the writer speaks in view of God's declaration, warning the wicked.
Lift . . . up the horn--to exalt power, here, of the wicked himself--that is, to be arrogant or self-elated.
speak . . . neck--insolently.
promotion--literally, "a lifting up." God is the only right judge of merit.
in the hand . . . a cup . . . red--God's wrath often thus represented (compare Isa 51:17 Jer 25:15).
but the dregs--literally, "surely the dregs, they shall drain it."
Contrasted is the lot of the pious who will praise God, and, acting under His direction, will destroy the power of the wicked, and exalt that of the righteous.
