19 All the first males to come to birth in your herd and your flock are to be holy to the Lord your God: the first birth of your ox is not to be used for work, the wool of your first lamb is not to be cut. 20 But year by year you and all your house are to take a meal of it before the Lord, in the place of his selection. 21 But if it has any mark on it, if it is blind or has damaged legs, or if there is anything wrong with it, it may not be offered to the Lord your God. 22 It may be used for food in your houses: the unclean and the clean may take of it, as of the gazelle and the roe. 23 Only do not take its blood for food, but let it be drained out on the earth like water.

(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.
