Psalms 136:1 An exhortation to give thanks to God for particular mercies.

(Title.)This Psalm is little else than a repetition of the preceding, with the addition of the burden, "for his mercy endureth for ever," at the end of each verse; and it was doubtless composed on the same occasion. It seems evidently to have been a responsive song; the first part of the verse being probably sung by the Levites, and the burden by the people.
Give thanks.
