Charles Ellicott Commentary Psalms 105:7-11

"He is Jehovah our God: His judgments are in all the earth. He hath remembered his covenant for ever, The word which he commanded to a thousand generations, [The covenant] which he made with Abraham, And his oath unto Isaac, And confirmed the same unto Jacob for a statute, To Israel for an everlasting covenant, Saying, Unto thee will I give the land of Canaan, The lot of your inheritance;" — Psalms 105:7-11 (ASV)

First cause of praise: the ancient covenant.
