The Pulpit Commentary
Unto thee, O God, do we give thanks, unto thee do we give thanks; for that thy Name is near thy wondrous works declare; literally, and thy Name is near (i.e. thy providence and care are close to us); this do thy wondrous works declare. The "wondrous works" are those of times past (comp. Psa_74:12-15), whereof the psalmist anticipates a continuance or repetition.

The Pulpit Commentary
When I shall receive the congregation; rather, when I shall have appointed a set time. It is agreed that the speaker, in this verse and the next, is God, who announces that he is about to descend in judgment. This, however, he will do "at his own set time," for which men must wait patiently (comp. Hab_2:3). I will judge uprightly; or, "with uprightness" (comp. Psa_58:1).

The Pulpit Commentary
The earth and all the inhabitants thereof are dissolved. They "melt" with fear (Psa_44:6), either at God's coming in judgment, or at the dissolution which a hostile invasion is bringing on their land. I bear up the pillars of it. Meanwhile God upholds, and will uphold, both the moral and physical order of things. He will neither suffer the earth to be moved, nor the supports on which society depends to fail and crumble away.

The Pulpit Commentary
I said. It is doubtful who is the speaker. Professor Cheyne regards the entire passage from the beginning of Psa_75:2 to the end of Psa_75:5 as spoken by the Almighty; but most commentators assign Psa_75:4 and Psa_75:5 to the psalmist or the people of Israel. Unto the fools; i.e. to the enemy which was attacking Israel; literally, to the boasters, or to the arrogant ones (see Revised Version). Deal not foolishly; rather, deal not so arrogantly. Do not set yourselves so proudly against the Almighty. And to the wicked, Lift not up the horn; i.e. be not fierce and menacing, like a bull who threatens with his horns.

The Pulpit Commentary
Lift not up your horn on high; speak not with a stiff neck. The phrase, "a stiff neck," common in the Pentateuch (Exo_32:9; Exo_33:3, Exo_33:5; Exo_34:9; Deu_9:6, Deu_9:13; Deu_10:16; Deu_31:27), is rare elsewhere. It expresses pride, arrogance, and obstinacy.

The Pulpit Commentary
For promotion cometh neither from the east, nor from the west, nor from the south. So Hupfeld, Kay, Canon Cook, and the Revised Version Others suggest the meaning to be, "For it is not from the east, nor is it from the west, nor yet from the mountainous desert [that help cometh]." But the ellipse of the main idea is improbable. The address is to the enemies who threaten Israel, "Lift not up your horns—speak not proudly—for exaltation comes not from any earthly quarter—east, west, north, or south" ("north" being omitted, as sufficiently implied in the others); it is God alone who gives it, and he is not likely to give it to you."

The Pulpit Commentary
But God is the Judge (comp. Psa_50:6; Psa_82:1; Psa_94:2; and, especially, the original of all the later passages, Gen_18:25). He putteth down one, and setteth up (or, exalteth) another. True equally of nations and of individuals.

The Pulpit Commentary
For in the hand of the Lord there is a cup, and the wine is red. The "cup of God's fury" is a frequent metaphor with the prophets (Isa_51:17, Isa_51:22; Jer_25:15, Jer_25:17, Jer_25:28; Jer_49:12; Lam_4:21; Eze_23:31-33; Hab_2:16, etc.); and is commonly represented as full of wine, which his enemies have to drink. The "redness" of the wine typifies the shedding of blood. It is full of mixture. Mingled, i.e; with spices, and so made stronger and more efficacious (see Pro_9:2; Pro_23:30; So Pro_8:2; Isa_5:22). And he poureth out of the same. God pours out the cup of his fury on all nations, or persons, whom he chooses to afflict, and they are compelled to drink of it (Jer_25:15-28). But the dregs thereof, all the wicked of the earth shall wring them out, and drink them. To drink a cup, dregs and all, is to empty it wholly, to swallow down all its contents.

The Pulpit Commentary
But I will declare forever; i.e. "I will declare these things"—viz. God's just judgments upon the wicked. I will sing praises to the God of Jacob. On the force of the phrase, "God of Jacob," see the comment upon Psa_20:1.

The Pulpit Commentary
All the horns of the wicked also will I cut off. Besides declaring God's judgments and singing his praises, the psalmist adds that he will, as far as lies in his power, seek to advance God's cause, and establish his kingdom, by checking, controlling, and putting down the wicked. This he expresses by the metaphor, "I will cut off their horns;" i.e. bring down their haughtiness, and deprive them of the power of doing mischief. But the horns of the righteous shall be exalted. Then, as a necessary consequence, "the horns of the righteous"—their power and might and glory—will be exalted.
