Summary of This Section.
“Therefore shall you keep my commandments, and do them. I am Yahweh. And you shall not profane my holy name, but I will be hallowed among the children of Israel. I am Yahweh who makes you holy, who brought you out of the land of Egypt, to be your God. I am Yahweh.”
So people and priests together are to keep Yahweh's commandments and do them. His holy Name must be honoured by their lives, and by their behaviour, and by their obedience so that His holiness is recognised and acknowledged. That is why He has made them holy, setting them apart as His people and delivering them and giving them His instruction (torah - Law). That is why He requires them to be holy. For they are His covenant people whom He has brought out of Egypt so that He could be their God. He is Yahweh. (There is no other).
