Book of Genesis 12,1-4a.

The LORD said to Abram: "Go forth from the land of your kinsfolk and from your father's house to a land that I will show you.
I will make of you a great nation, and I will bless you; I will make your name great, so that you will be a blessing.
I will bless those who bless you and curse those who curse you. All the communities of the earth shall find blessing in you."
Abram went as the LORD directed him, and Lot went with him. Abram was seventy-five years old when he left Haran.
