Exodus 10:7-9

Young's Literal Translation

⁷ And the servants of Pharaoh say unto him, `Until when doth this [one] become a snare to us? send the men away, and they serve Jehovah their God; knowest thou not yet that Egypt hath perished?'

⁸ And Moses is brought back -- Aaron also -- unto Pharaoh, and he saith unto them, `Go, serve Jehovah your God; -- who and who [are] those going?'

⁹ And Moses saith, `With our young ones, and with our aged ones, we go, with our sons, and with our daughters, with our flock, and our herd, we go, for we have a festival to Jehovah.'
