Leviticus Chapter 23

23:2-4
Speak unto the children of Israel, and say unto them, Concerning the feasts of the Lord, which ye shall proclaim to be holy convocations, even these are my feasts.
Six days shall work be done: but the seventh day is the sabbath of rest, an holy convocation; ye shall do work therein: it is the sabbath of the Lord in all your dwellings.
These are the feasts of the Lord, even holy convocations, which ye shall proclaim in their seasons.

23:10
Speak unto the children of Israel, and say unto them, When ye be come into the land which I give unto you, and shall reap the harvest thereof, then ye shall bring a sheaf of the firstfruits of your harvest unto the priest:

23:14
And ye shall eat neither bread, nor parched corn, nor green ears, until the selfsame day that ye have brought an offering unto your God: it shall be a statute for ever throughout your generations in all your dwellings.

23:22
And when ye reap the harvest of your land, thou shalt not make clean riddance of the corners of thy field when thou reapest, neither shalt thou gather any gleaning of thy harvest: thou shalt leave them unto poor, and to the stranger: I am the Lord your God.

23:40-44
And ye shall take you on the first day the boughs of goodly trees, branches of palm trees, and the boughs of thick trees, and willows of the brook; and ye shall rejoice before the Lord your God seven days.
And ye shall keep it a feast unto the Lord seven days in the year. It shall be a statute for ever in your generations: ye shall celebrate it in the seventh month.
Ye shall dwell in booths seven days; all that are Israelites born shall dwell in booths:
That your generations may know that I made the children of Israel to dwell in booths, when I brought them out of the land of Egypt: I am the Lord your God.
And Moses declared unto the children of Israel the feasts of the Lord.
