Albert Barnes Commentary Psalms 108:3

"I will give thanks unto thee, O Jehovah, among the peoples; And I will sing praises unto thee among the nations." — Psalms 108:3 (ASV)

I will praise thee, O Lord ... - This is taken from (Psalms 57:9). The only change is the substitution here of the name יהוה Yahweh for אדני 'Adonāy. Why that change was made is unknown.
