'God of Heaven' in the Bible

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

The Lord, the God of heaven, who took me from my father’s house and from my native land, who spoke to me and swore to me, ‘I will give this land to your offspring’—He will send His angel before you, and you can take a wife for my son from there.
