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

19 “Every male firstborn that will be born in your herd and in your flock you should sanctify to Jehovah your God.+ You must do no service with the firstborn of your bull, nor shear the firstborn of your flock.+
