This psalm has no title in Hebrew; and the author, and the occasion on which it was written, are alike unknown. It is general in its character, though its imagery is taken mostly from Hebrew history.
The sole design of the psalm is to excite to the praise of God; or to show reasons for that praise. As grounds or reasons for this, the psalmist refers to the fact that God is good, Psalms 135:3; to the fact that he had chosen Jacob for himself, Psalms 135:4; to the greatness of God as seen in the works of nature, Psalms 135:5-7; to the history of the Hebrew people, Psalms 135:8-12; to the inability of idols to aid, Psalms 135:13-18; and, in view of all this, he calls on all classes of the people to praise the Lord, Psalms 135:19-21.
