Albert Barnes Commentary Psalms 107:15

"Oh that men would praise Jehovah for his lovingkindness, And for his wonderful works to the children of men!" — Psalms 107:15 (ASV)

Oh that men would praise ... - See the notes at (Psalms 107:8). The idea here is that the things just referred to should call forth expressions of gratitude to God. The immediate reference is to those who had partaken of these proofs of the divine goodness, but still the language is so general as to be applicable to all classes of people.
