'Friend' in the Bible

"LORD God of our ancestors, you are the God who lives in heaven, are you not? You rule over all the kingdoms of the nations, don't you? In your own hands you grasp both strength and power, don't you? As a result, no one can oppose you, can they? You are our God, who expelled the former inhabitants of this land right in front of our people Israel, aren't you? Then you gave it to your friend Abraham's descendant forever, didn't you?
