'First fruits' in the Bible

And the feast of harvest, the first-fruits of thy labors, which thou hast sown in the field: and the feast of in-gathering, which is in the end of the year, when thou hast gathered in thy labors out of the field.

The first of the first-fruits of thy land thou shalt bring into the house of the LORD thy God. Thou shalt not seethe a kid in his mother's milk.

And thou shalt observe the feast of weeks, of the first-fruits of wheat-harvest, and the feast of in-gathering at the year's end.

The first of the first-fruits of thy land thou shalt bring to the house of the LORD thy God. Thou shalt not seethe a kid in his mother's milk.
