Albert Barnes Commentary Psalms 37:5

"Commit thy way unto Jehovah; Trust also in him, and he will bring it to pass." — Psalms 37:5 (ASV)

Commit thy way unto the LORD. Margin, as in Hebrew, “Roll your way upon the Lord.” Compare the notes at (Psalms 22:8), where the margin, as the Hebrew, is, “He rolled himself on the Lord.” See also (1 Peter 5:7). The idea is that of rolling a heavy burden from ourselves on another, or laying it upon him, so that he may bear it. The burden which we do not have strength to bear we may lay on God.

The term “way” properly means the act of treading or going; then, a way or path; then, a course of life, or the manner in which one lives. The reference here is to the whole course of life, or all that can affect life; all our plans or conduct; all the issues or results of those plans. It is equivalent here to “lot” or “destiny.” Everything regarding the manner in which we live, and all its results, is to be committed to the Lord.

Trust also in him. See (Psalms 37:3).

And he shall bring it to pass. Hebrew, “He shall do it.” That is, He will bring it to a proper issue; He will secure a happy result. He will take care of your interests, and will not permit you to suffer, or to be ultimately wronged. The thing particularly referred to here, as appears from the next verse, is reputation or character.
