'God of Heaven' in the Bible

that I may make you swear by Yahweh, the God of heaven and the God of earth, that you will not take a wife for my son from the daughters of the Canaanites in whose midst I am dwelling,

Yahweh, the God of heaven who took me from the house of my father and from the land of my family, and who spoke to me and swore to me, saying, 'to your offspring I will give this land,' he will send his angel before you, and you shall take a wife for my son from there.
