Psalms 105:7-11

God remembered His people (Psalms 105:7, cf. Psalms 105:42), so His people should remember Him (Psalms 105:5). God had been faithful to the Abrahamic Covenant (Genesis 12:1-3; Genesis 12:7; Genesis 15:18-21; Genesis 22:15-18; Genesis 28:13-15). He made this covenant with Abraham’s descendants as well as with him personally. A "thousand generations" means innumerable generations (cf. Exodus 20:5-6). Note that the psalmist called this covenant an "everlasting covenant" (Psalms 105:10). That is, it would abide in effect as long at the earth abides. Of the three promises in the covenant, the writer mentioned only the land promise here.
