'Deceit' in the Bible

And Moses said, When I go out from you I will make prayer to the Lord that the cloud of flies may go away from Pharaoh and from his people and from his servants tomorrow: only let Pharaoh no longer by deceit keep back the people from making their offering to the Lord.

But if a man makes an attack on his neighbour on purpose, to put him to death by deceit, you are to take him from my altar and put him to death.
