TSK · Exodus 22:29

that you shall set apart to Yahweh all that opens the womb, and every firstborn which you have that comes from an animal. The males shall be Yahweh's.

The first of the first fruits of your ground you shall bring into the house of Yahweh your God. "You shall not boil a young goat in its mother's milk.

"When a bull, or a sheep, or a goat, is born, then it shall remain seven days with its mother; and from the eighth day and thenceforth it shall be accepted for the offering of an offering made by fire to Yahweh.

All the firstborn males that are born of your herd and of your flock you shall sanctify to Yahweh your God: you shall do no work with the firstborn of your herd, nor shear the firstborn of your flock.

A man from Baal Shalishah came, and brought the man of God bread of the first fruits, twenty loaves of barley, and fresh ears of grain in his sack. He said, "Give to the people, that they may eat."

Honor Yahweh with your substance, with the first fruits of all your increase:

Misery is mine! Indeed, I am like one who gathers the summer fruits, as gleanings of the vineyard: There is no cluster of grapes to eat. My soul desires to eat the early fig.

Not only so, but ourselves also, who have the first fruits of the Spirit, even we ourselves groan within ourselves, waiting for adoption, the redemption of our body.
