Exodus 10:24-26

Young's Literal Translation

²⁴ And Pharaoh calleth unto Moses and saith, `Go ye, serve Jehovah, only your flock and your herd are stayed, your infants also go with you;'

²⁵ and Moses saith, `Thou also dost give in our hand sacrifices and burnt-offerings, and we have prepared for Jehovah our God;

²⁶ and also our cattle doth go with us, there is not left a hoof, for from it we do take to serve Jehovah our God; and we -- we know not how we do serve Jehovah till our going thither.'
