The psalmist exhorts the seed of Abraham (Psalms 105:6) to give thanks to God and call upon his Name (Psalms 105:1-3); to make him known among the Gentiles (Psalms 105:1); to seek him and his strength (Psalms 105:4); and to bear in mind his marvellous works (Psalms 105:5).
The "works" intended are those of his providential government of mankind, and especially those of his rule and government over his people Israel.
