“Every firstling male born of your herd and flock you shall consecrate to Yahweh your God. You shall not do work with your firstling ox nor shear the firstling of your flock. You shall eat it, you together with your household, in the presence of Yahweh your God year by year at the place that Yahweh will choose. But if it has any defect or blemish, any serious defect or blemish, such as lameness or blindness, you shall not sacrifice it to Yahweh your God. Within your towns, you may eat it, the unclean and the clean alike, as you would a gazelle or a deer. Its blood, however, you must not eat. You shall pour it out on the ground like water.”
This is like Exodus, chapter 13. You must set aside the first-born of your herd and flock to be eaten at the place where Yahweh will choose. These animals should not be worked or sheared. Obviously the first-born should be without blemish, the most serious defect was being lame or blind. However, you can eat the blemished animal just like you would a deer in your own town. Nevertheless, you should not eat the blood, but rather throw it on the ground like water.
