Genesis 12:1-3 ESV
Now the Lord said to Abram, “Go from your country and your kindred and your father’s house to the land that I will show you. And I will make of you a great nation, and I will bless you and make your name great, so that you will be a blessing. I will bless those who bless you, and him who dishonors you I will curse, and in you all the families of the earth shall be blessed."
Exodus 34:6-7 ESV
6 The Lord passed before him and proclaimed, "The Lord, the Lord, a God merciful and gracious, slow to anger, and abounding in steadfast love and faithfulness, 7 keeping steadfast love for thousands, forgiving iniquity and transgression and sin, but who will by no means clear the guilty, visiting the iniquity of the fathers on the children and the children's children, to the third and the fourth generation."
