19Every firstborn male that is born of your cattle and of your flock you shall consecrate to the LORD your God; you shall not work the firstborn of your cattle, and you shall not shear the firstborn of your flock.20You shall eat it before the LORD your God year by year in the place that the LORD shall choose, you and your household.21But if it has a blemish, lame or blind or any harmful blemish, you shall not sacrifice it to the LORD your God.22You shall eat it within your gates, the unclean and the clean together, as the gazelle and as the deer.23Only its blood you shall not eat; you shall pour it out on the land like water.
