17 You will not be allowed to eat within your cities* the tenth part of your grain, your new wine, your oil, the firstborn of your herd and flock,+ any of your vow offerings that you vow, your voluntary offerings, or the contribution from your hand.

19 “You should sanctify every firstborn male of your herd and your flock to Jehovah your God.+ You must not do any work with the firstborn of your herd* nor shear the firstborn of your flock.
