David had said he would keep God's word (Psa 119:57), and it was well said; now here he tells us how and in what method he pursued that resolution. 1. He thought on his ways. He thought beforehand what he should do, pondering the path of his feet (Pro 4:26), that he might walk surely, and not at all adventures. He thought after what he had done, reflected upon his life past, and recollected the paths he had walked in and the steps he had taken. The word signifies a fixed abiding thought. Some make it an allusion to those who work embroidery, who are very exact and careful to cover the least flaw, or to those who cast up their accounts, who reckon with themselves, What do I owe? What am I worth? "I thought not on my wealth (as the covetous man, Psa 49:11) but on my ways, not on what I have, but what I do:" for what we do will follow us into another world when what we have must be left behind. Many are critical enough in their remarks upon other people's ways who never think of their own: but let every man prove his own work. 2. He turned his feet to God's testimonies. He determined to make the word of God his rule, and to walk by that rule. He turned from the by-paths to which he had turned aside, and returned to God's testimonies. He turned not only his eye to them, but his feet, his affections to the love of God's word and his conversation to the practice of it. The bent and inclinations of his soul were towards God's testimonies and his conversation was governed by them Penitent reflections must produce pious resolutions. 3. He did this immediately and without demur (Psa 119:60): I made haste and delayed not. When we are under convictions of sin we must strike while the iron is hot, and not think to defer the prosecution of them, as Felix did, to a more convenient season. When we are called to duty we must lose no time, but set about it today, while it is called today. Now this account which David here gives of himself may refer either to his constant practice every day (he reflected on his ways at night, directed his feet to God's testimonies in the morning, and what his hand found to do that was good he did it without delay), or it may refer to his first acquaintance with God and religion, when he began to throw off the vanity of childhood and youth, and to remember his Creator; that blessed change was, by the grace of God, thus wrought. Note, (1.) Conversion begins in serious consideration, Eze 18:28; Luk 15:17. (2.) Consideration must end in a sound conversion. To what purpose have we thought on our ways if we do not turn our feet with all speed to God's testimonies?

At midnight I will rise to give thanks unto thee,.... Not only send up an ejaculatory thanksgiving upon his bed, but rise up from it and shake off his sleep, and in a set, serious, solemn manner, praise the Lord. This shows a great regard to him, and affection to this work, since it is with difficulty men prevail upon themselves to rise at midnight upon any occasion; at midnight Paul and Silas prayed and sung praises to God, Act 16:25;

because of thy righteous judgments; upon the wicked, as Aben Ezra; the hands and troops of them that encompassed him about, and robbed him; but God avenged him of them, and for this he gave thanks, or for such like things. Sometimes the judgments of God have been executed at midnight; as the destruction of the firstborn in Egypt, and of Pharaoh and his host in the Red sea, when Israel sang his praise, Exo 12:29; and for the judgments of God upon antichrist the church will rejoice and give thanks, Rev 18:20. Or rather by these may be meant the word of God, the precepts and ordinances of it, which are all just and good; such is the law of God, and such are the ordinances of Christ, Psa 19:9.
