'Themselves' in the Bible

And he said to me, "Get up, go down at once from here because your people whom you brought out of Egypt have sinned! They have quickly turned from the way I commanded them and have made for themselves a cast metal image."

Then the Lord said to Moses, "The day of your death is near. Summon Joshua and present yourselves in the tent of meeting so that I can commission him." So Moses and Joshua presented themselves in the tent of meeting.

Then the Lord said to Moses, "You are about to die, and then these people will begin to prostitute themselves with the foreign gods of the land into which they are going. They will reject me and break my covenant that I have made with them.
