'Friend' in the Bible

He told them, "This is what the LORD, the God of Israel, says, "Every man put his sword on his thigh, and go back and forth from gate to gate in the camp, and each of you kill his brother and friend and neighbor.'"

The LORD would speak to Moses face to face just as a man speaks with his friend. When Moses returned to the camp, Nun's son Joshua, his young servant, would not leave the tent.
