30 This is what you should do with your bull and your sheep:+ Seven days it will continue with its mother. On the eighth day, you are to give it to me.+

13 For every firstborn is mine.+ In the day that I struck every firstborn in the land of Egypt,+ I sanctified to myself every firstborn in Israel from man to beast.+ They are to become mine. I am Jehovah.”

15 “Every firstborn of all living things,*+ which they will present to Jehovah, whether man or animal, should become yours. However, you should without fail redeem the firstborn of mankind,+ and the firstborn of the unclean animals you should redeem.+

17 Only the firstborn bull or firstborn male lamb or firstborn goat you should not redeem.+ They are something holy. You should sprinkle their blood on the altar,+ and their fat you should make smoke as an offering made by fire for a pleasing* aroma to Jehovah.+
