Exodus 23:19

The first of the firstfruits of thy land thou shalt bring unto the house of the LORD thy God. Thou shalt not seethe a kid in his mother’s milk.

Ye shall not eat of anything that dieth of itself: thou shalt give it unto the stranger that is in thy gates, that he may eat it; or thou mayest sell it unto an alien: for thou art an holy people unto the LORD thy God. Thou shalt not seethe a kid in his mother’s milk.

And now, behold, I have brought the firstfruits of the land, which thou, O LORD, hast given me. And thou shalt set it before the LORD thy God, and worship before the LORD thy God:

Thou shalt not delay to offer the first of thy ripe fruits, and of thy liquors: the firstborn of thy sons shalt thou give unto me.

And to bring the firstfruits of our ground, and the firstfruits of all fruit of all trees, year by year, unto the house of the LORD:

That thou shalt take of the first of all the fruit of the earth, which thou shalt bring of thy land that the LORD thy God giveth thee, and shalt put it in a basket, and shalt go unto the place which the LORD thy God shall choose to place his name there.

A righteous man regardeth the life of his beast: but the tender mercies of the wicked are cruel.

But now is Christ risen from the dead, and become the firstfruits of them that slept.

For the customs of the people are vain: for one cutteth a tree out of the forest, the work of the hands of the workman, with the axe.

These are they which were not defiled with women; for they are virgins. These are they which follow the Lamb whithersoever he goeth. These were redeemed from among men, being the firstfruits unto God and to the Lamb.
