Exodus 10:8-11

10:8 So Moses and Aaron were brought back to Pharaoh, and he said to them, “Go, serve the Lord your God. Exactly who is going with you?” 10:9 Moses said, “We will go with our young and our old, with our sons and our daughters, and with our sheep and our cattle we will go, because we are to hold a pilgrim feast for the Lord.”

10:10 He said to them, “The Lord will need to be with you if I release you and your dependents! Watch out! Trouble is right in front of you! 10:11 No! Go, you men only, and serve the Lord, for that is what you want.” Then Moses and Aaron were driven out of Pharaoh’s presence.

Exodus 10:24-27

10:24 Then Pharaoh summoned Moses and said, “Go, serve the Lord – only your flocks and herds will be detained. Even your families may go with you.”

10:25 But Moses said, “Will you also provide us with sacrifices and burnt offerings that we may present them to the Lord our God? 10:26 Our livestock must also go with us! Not a hoof is to be left behind! For we must take these animals to serve the Lord our God. Until we arrive there, we do not know what we must use to serve the Lord.”

10:27 But the Lord hardened Pharaoh’s heart, and he was not willing to release them.
