| Barnes' Notes on the Bible Let those that fear thee turn unto me - Let thy friends be my friends. Let them show me favor, and count me among their companions. If the great and the powerful turn away from me; if they persecute me, and do me wrong; if they cast out my name as evil, and are unwilling to associate with me, yet let thy friends, however poor and humble, regard me with kindness, and reckon me among their number, and I shall be satisfied. And those that have known thy testimonies - Thy law. Those who can see and appreciate the beauty of thy commandments. This is the ground of true friendship in religion - the common love of God, of his law, and of his service. This is a permanent ground of affection. All friendship founded on earthly distinctions; all derived from titled birth - from rank - from affluence - from civil, military, or naval renown - from beauty, strength, or nobleness of form - must be temporary; but that which is founded on attachment to God, to his law, and to the Saviour, will abide forever.
Clarke's Commentary on the BibleLet those that fear thee - The truly pious. Turn unto me - Seeing thy work upon me, they shall acknowledge me as a brand plucked from the burning.
Gill's Exposition of the Entire BibleLet those that fear thee turn unto me,.... Whose companion he was fond of being, Psalm 119:63; There were some good men, it seems, that turned from him, took the part of his enemies, and sided with them against him, which was matter of grief to him. Some think this refers to the affair of Bathsheba; when some that feared the Lord, that had been familiar with him, did not choose to keep company with him, but abstained from his conversation, having so foully sinned, and brought forth dishonour to God and on his ways. Jarchi and Kimchi both make mention of this. Now this grieved David; and he desires of all things that they would turn to him again, and favour him with their company; who were the excellent in the earth, in whom was all his delight. The Targum is, "turn to my doctrine;'' to hear it, receive it, profess it, and abide by it; and those that have known thy testimonies; as such as fear the Lord do: they know them, and have a spiritual understanding of what they testify of; they know them, and love them, and delight in them; they know them, and own, acknowledge, and profess them; they know them, and keep, and observe them; and an excellent character this is.

Jamieson-Fausset-Brown Bible Commentary79, 80. Those who may have thought his afflictions an evidence of God's rejection will then be led to return to Him; as the friends of Job did on his restoration, having been previously led through his afflictions to doubt the reality of his religion.
Matthew Henry's Concise Commentary119:73-80 God made us to serve him, and enjoy him; but by sin we have made ourselves unfit to serve him, and to enjoy him. We ought, therefore, continually to beseech him, by his Holy Spirit, to give us understanding. The comforts some have in God, should be matter of joy to others. But it is easy to own, that God's judgments are right, until it comes to be our own case. All supports under affliction must come from mercy and compassion. The mercies of God are tender mercies; the mercies of a father, the compassion of a mother to her son. They come to us when we are not able to go to them. Causeless reproach does not hurt, and should not move us. The psalmist could go on in the way of his duty, and find comfort in it. He valued the good will of saints, and was desirous to keep up his communion with them. Soundness of heart signifies sincerity in dependence on God, and devotedness to him.
Matthew Henry's Whole Bible CommentaryVerses 78-79 Here David shows, I. How little he valued the will-will of sinners. There were those that dealt perversely with him, that were peevish and ill-conditioned towards him, that sought advantages against him, and misconstrued all he said and did. Even those that deal most fairly may meet with those that deal perversely. But David regarded it not, for, 1. He knew it was without cause, and that for his love they were his adversaries. The causeless reproach, like the curse causeless, may be easily slighted; it does not hurt us, and therefore should not move us. 2. He could pray, in faith, that they might be ashamed of it; God's dealing favourably with him might make them ashamed to think that they had dealt perversely with him. "Let them be ashamed, that is, let them be brought either to repentance or to ruin." 3. He could go on in the way of his duty, and find comfort in that. "However they deal with me, I will meditate in thy precepts, and entertain myself with them." II. How much he valued the good-will of saints, and how desirous he was to stand right in their opinion, and keep up his interest in them and communion with them: Let those that fear thee turn to me. He does not mean so much that they might side with him, and take up arms in his cause, as that they might love him, and pray for him, and associate with him. Good men desire the friendship and society of those that are good. Some think it intimates that when David had been guilty of that foul sin in the murder of Uriah, though he was a king, those that feared God grew strange to him and turned from him, for they were ashamed of him; this troubled him, and therefore he prays, Lord, let them turn to me again. He desires especially the company of those that were not only honest, but intelligent, that have known thy testimonies, have good heads as well as good hearts, and whose conversation will be edifying. It is desirable to have an intimacy with such. |
