Psalm 105:4-9 and Genesis 17:3-9

Psalm 105:4-9
4 Seek the Lord, and be confirmed. Seek his face always.
5 Remember his miracles, which he has done, his portents and the judgments of his mouth:
6 you offspring of Abraham his servant, you sons of Jacob his elect.
7 He is the Lord our God. His judgments are throughout the entire earth.
8 He has remembered his covenant for all ages: the word that he entrusted to a thousand generations,
9 which he assigned to Abraham, and his oath to Isaac. 
Genesis 17:3-9
​3 Abram fell prone on his face.
4 And God said to him: "I AM, and my covenant is with you, and you will be the father of many nations.
5 No longer will your name be called Abram. But you will be called Abraham, for I have established you as the father of many nations.
6 And I will cause you to increase very greatly, and I will set you among the nations, and kings will come forth from you.
7 And I will establish my covenant between me and you, and with your offspring after you in their generations, by a perpetual covenant: to be God to you and to your offspring after you.
8 And I will give to you and to your offspring, the land of your sojourn, all the land of Canaan, as an eternal possession, and I will be their God."
9 Again God said to Abraham: "And you therefore shall keep my covenant, and your offspring after you in their generations.
