Exodus 10:7-9

American Standard Version

⁷ And Pharaoh’s servants said unto him, How long shall this man be a snare unto us? let the men go, that they may serve Jehovah their God: knowest thou not yet that Egypt is destroyed? ⁸ And Moses and Aaron were brought again unto Pharaoh: and he said unto them, Go, serve Jehovah your God; but who are they that shall go? ⁹ And Moses said, We will go with our young and with our old; with our sons and with our daughters, with our flocks and with our herds will we go; for we must hold a feast unto Jehovah.
