Psalms 2:4

“He that sitteth in the heavens shall laugh, etc.] At the rage and tumult of the Heathen; at the vain imaginations of the people; at the opposition of the kings of the earth; at the mad counsel of the rulers, against him and his Messiah; and at their proposal to one another to throw off the yoke and government of them both. This is a periphrasis of God, “who dwells in the heavens”, and sits there enthroned; though he is not included and comprehended in them, but is everywhere; and his being there is mentioned in opposition to the kings of the earth, and the people in it; and to show the vast distance there is between them, and how they are as nothing to him, (<234001>Isaiah 40:1,5,17,22)…”

“By a figure whose boldness is only allowable to an inspired writer, God's conduct and language in view of this opposition are now related. He that sitteth in the heavens--enthroned in quiet dignities (compare Psa 29:10; Isa 40:22). shall laugh--in supreme contempt; their vain rage excites His derision. He is still the Lord, literally, "Sovereign," though they rebel.”

“He that sitteth in the heavens - God, represented as having his home, his seat, his throne in heaven, and thence administering the affairs of the world. This verse commences the second strophe or stanza of the psalm; and this strophe Psalms 2:4-6 corresponds with the first Psalms 2:1-3 in its structure. The former describes the feelings and purposes of those who would cast off the government of God; this describes the feelings and purposes of God in the same order, for in each case the psalmist describes what is done, and then what is said: the nations rage tumultuously Psalms 2:1-2, and then say Psalms 2:3, “Let us break their bands.” God sits calmly in the heavens, smiling on their vain…”

“Sitteth - As the king of the whole world. Heavens - As an evidence both of God's clear and certain knowledge of all things that are done below, and of his sovereign and irresistible power. Laugh - Shall despise them and all their crafty devices. Psalms 2:6”

“2:4-6 The Lord finds the human threat insignificant. He provided a solution long before their rebellion. He will end their agitation through the appointment of a human agent, a descendant of David’s line who will rule the nations. 2:4 rules in heaven: The Lord’s place in the universe is so certain that he scoffs at humans who boast that they can rebel against his power and authority (see 37:13; 59:8).”

“He that: Psa 11:4, Psa 68:33, Psa 115:3; Isa 40:22, Isa 57:15, Isa 66:1 shall laugh: Psa 37:13, Psa 53:5, Psa 59:8; Kg2 19:21; Pro 1:26 Psalms 2:5”

“Above the scene of this wild tumult of battle and imperious arrogance the psalmist in this six line strophe beholds Jahve, and in spirit hears His voice of thunder against the rebels. In contrast to earthly rulers and events Jahve is called יושׁב בּשּׁמים: He is enthroned above them in unapproachable majesty and ever-abiding glory; He is called אדני as He who controls whatever takes place below with absolute power according to the plan His wisdom has devised, which brooks no hindrance in execution. The futt. describe not what He will do, but what He does continually (cf. Isa 18:4.). למו also belongs, according to Psa 59:9; Psa 37:13, to ישׂחק (שׂחק which is more usual in the…”
