At midnight I will rise to give thanks unto thee because of thy righteous judgments.

Jamieson-Fausset-Brown Bible Commentary

62. At midnight-Hengstenberg supposes a reference to the time when the Lord went forth to slay the Egyptian first-born (Ex 11:4; 12:29; compare Job 34:20). But it rather refers to the Psalmist's own praises and prayers in the night time. Compare Paul and Silas (Ac 16:25; compare Ps 63:6).

Matthew Henry's Concise Commentary

119:57-64 True believers take the Lord for the portion of their inheritance, and nothing less will satisfy them. The psalmist prayed with his whole heart, knowing how to value the blessing he prayed for: he desired the mercy promised, and depended on the promise for it. He turned from by-paths, and returned to God's testimonies. He delayed not. It behoves sinners to hasten to escape; and the believer will be equally in haste to glorify God. No care or grief should take away God's word out of our minds, or hinder the comfort it bestows. There is no situation on earth in which a believer has not cause to be thankful. Let us feel ashamed that others are more willing to keep from sleep to spend the time in sinful pleasures, than we are to praise God. And we should be more earnest in prayer, that our hearts may be filled with his mercy, grace, and peace.

Matthew Henry's Whole Bible Commentary

Verse 62

Though David is, in this psalm, much in prayer, yet he did not neglect the duty of thanksgiving; for those that pray much will have much to give thanks for. See, 1. How much God's hand was eyed in his thanksgivings. He does not say, "I will give thanks because of thy favours to me, which I have the comfort of," but, "Because of thy righteous judgments, all the disposals of thy providence in wisdom and equity, which thou hast the glory of." We must give thanks for the asserting of God's honour and the accomplishing of his word in all he does in the government of the world. 2. How much David's heart was set upon his thanksgivings. He would rise at midnight to give thanks to God. Great and good thoughts kept him awake, and refreshed him, instead of sleep; and so zealous was he for the honour of God that when others were in their beds he was upon his knees at his devotions. He did not affect to be seen of men in it, but gave thanks in secret, where our heavenly Father sees. He had praised God in the courts of the Lord's house, and yet he will do it in his bed-chamber. Public worship will not excuse us from secret worship. When David found his heart affected with God's judgments, he immediately offered up those affections to God, in actual adorations, not deferring, lest they should cool. Yet observe his reverence; he did not lie still and give thanks, but rose out of his bed, perhaps in the cold and in the dark, to do it the more solemnly. And see what a good husband he was of time; when he could not lie and sleep, he would rise and pray.
