19 Consecrate to God, your God, all the firstborn males in your herds and flocks. Don't use the firstborn from your herds as work animals; don't shear the firstborn from your flocks. 20 These are for you to eat every year, you and your family, in the Presence of God, your God, at the place that God designates for worship. 21 If the animal is defective, lame, say, or blind - anything wrong with it - don't slaughter it as a sacrifice to God, your God. 22 Stay at home and eat it there. Both the ritually clean and unclean may eat it, the same as with a gazelle or a deer. 23 Only you must not eat its blood. Pour the blood out on the ground like water.

Commentary on Deuteronomy 15:19-23
(Read Deuteronomy 15:19-23)
Here is a direction what to do with the firstlings. We are not now limited as the Israelites were; we make no difference between a first calf, or lamb, and the rest. Let us then look to the gospel meaning of this law, devoting ourselves and the first of our time and strength to God; and using all our comforts and enjoyments to his praise, and under the direction of his law, as we have them all by his gift.
