'Serve the Lord' in the Bible

Pharaoh’s servants said to him, “How long shall this man be a trap to us? Let the men go, so that they may serve the Lord their God. Do you not realize that Egypt is destroyed?”

So Moses and Aaron were brought back to Pharaoh, and he said to them, “Go, serve the Lord your God! Who specifically are the ones that are going?”

No! Go now, you who are men, [without your families] and serve the Lord, if that is what you want.” So Moses and Aaron were driven from Pharaoh’s presence.

Then Pharaoh called to Moses, and said, “Go, serve the Lord; only your flocks and your herds must be left behind. Even your children may go with you.”

Therefore, our livestock must also go with us; not one hoof shall be left behind, for we must take some of them to serve the Lord our God. Even we do not know with what we will serve the Lord until we arrive there.”

Then he called for Moses and Aaron at night and said, “Get up, get out from among my people, both you and the Israelites; and go, serve the Lord, as you said.

You shall serve [only] the Lord your God, and He shall bless your bread and water. I will also remove sickness from among you.
