Ge 32:1 So Jacob went on his way, and the angels of God met him.

2 When Jacob saw them, he said, "This is God's camp." And he called the name of that place Mahanaim.

Mahanaim was part of the Promise Land. It's in the territory of Israel. Moses is again encouraging his original Israelite readers that the place they are going to is where God's angels met their forefather Jacob. It is a place called "God's camp." It's a further encouragement to go and occupy the land and not turn back to Egypt.
