Genesis 24:3; Genesis 24:7

3 and I will make you swear by the LORD , the God of heaven and the God of earth, that you shall not take a wife for my son from the daughters of the Canaanites, among whom I live,

7 "The LORD , the God of heaven, who took me from my father's house and from the land of my birth, and who spoke to me and who swore to me, saying, 'To your descendants I will give this land,' He will send His angel before you, and you will take a wife for my son from there.
