| Barnes' Notes on the Bible I made haste - This language further describes the process of conversion. There was no delay; there was no excuse offered. He acted at once under his conviction of what was right. He did not ask permission to defer it to a future time; he did not attempt to avoid the duty; not plead inability; he did not give himself merely to the "use of means;" he did not rely on prayer, and reading, and reflection; but "he did the thing, and he did it at once." This is conversion; and if all convicted sinners would follow this example, and do at once that which they are commanded to do, and which they know they ought to do, there would be in no case any difficulty about conversion, for the main difficulty in conversion lies in the fact that the sinner is not willing to obey God at once; that he will not break away from his sins; that he endeavors to excuse himself; that he pleads for delay; that he waits for God to do what he himself ought to do. And delayed not to keep thy commandments - I did not continue to go on in a course of sin, but I forsook my sin and obeyed.
Clarke's Commentary on the BibleThirdly. I made haste, and delayed not - He did this with the utmost speed; and did not trifle with his convictions, nor seek to drown the voice of conscience. The original word, which we translate delayed not, is amazingly emphatical. ולא התמהמהתי velo hithmahmahti, I did not stand what-what-whating; or, as we used to express the same sentiment, shilly-shallying with myself: I was determined, and so set out. The Hebrew word, as well as the English, strongly marks indecision of mind, positive action being suspended, because the mind is so unfixed as not to be able to make a choice.
Gill's Exposition of the Entire BibleI made haste, and delayed not to keep thy commandments. As soon as he was sensible of his duty, he immediately complied with it; he consulted not with flesh and blood, but at once yielded a cheerful obedience to the commands of God. Instances of evangelical obedience of this kind we have in the three thousand converts, in Saul, and in the jailer and his house, Acts 2:41.

Matthew Henry's Concise Commentary119:57-64 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 CommentaryVerses 59-60 David had said he would keep God's word (v. 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 (Prov. 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, Ps. 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 (v. 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 to-day, while it is called to-day. 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; Lu. 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? |
