Acts 2:1

And the feast of harvest, the firstfruits of thy labors, which thou hast sown in the field: and the feast of ingathering, which is in the end of the year, when thou hast gathered in thy labors out of the field.

And thou shalt observe the feast of weeks, of the firstfruits of wheat harvest, and the feast of ingathering at the year's end.

And ye shall count unto you from the morrow after the sabbath, from the day that ye brought the sheaf of the wave offering; seven sabbaths shall be complete: Even unto the morrow after the seventh sabbath shall ye number fifty days; and ye shall offer a new meat offering unto the LORD. Ye shall bring out of your habitations two wave loaves of two tenth deals; they shall be of fine flour; they shall be baked with leaven; they are the firstfruits unto the LORD. And ye shall offer with the bread seven lambs without blemish of the first year, and one young bullock, and two rams: they shall be for a burnt offering unto the LORD, with their meat offering, and their drink offerings, even an offering made by fire, of sweet savor unto the LORD. Then ye shall sacrifice one kid of the goats for a sin offering, and two lambs of the first year for a sacrifice of peace offerings. And the priest shall wave them with the bread of the firstfruits for a wave offering before the LORD, with the two lambs: they shall be holy to the LORD for the priest. And ye shall proclaim on the selfsame day, that it may be an holy convocation unto you: ye shall do no servile work therein: it shall be a statute for ever in all your dwellings throughout your generations.

And in the fourteenth day of the first month is the passover of the LORD. And in the fifteenth day of this month is the feast: seven days shall unleavened bread be eaten. In the first day shall be an holy convocation; ye shall do no manner of servile work therein: But ye shall offer a sacrifice made by fire for a burnt offering unto the LORD; two young bullocks, and one ram, and seven lambs of the first year: they shall be unto you without blemish: And their meat offering shall be of flour mingled with oil: three tenth deals shall ye offer for a bullock, and two tenth deals for a ram; A several tenth deal shalt thou offer for every lamb, throughout the seven lambs: And one goat for a sin offering, to make an atonement for you. Ye shall offer these beside the burnt offering in the morning, which is for a continual burnt offering. After this manner ye shall offer daily, throughout the seven days, the meat of the sacrifice made by fire, of a sweet savor unto the LORD: it shall be offered beside the continual burnt offering, and his drink offering. And on the seventh day ye shall have an holy convocation; ye shall do no servile work. Also in the day of the firstfruits, when ye bring a new meat offering unto the LORD, after your weeks be out, ye shall have an holy convocation; ye shall do no servile work: But ye shall offer the burnt offering for a sweet savor unto the LORD; two young bullocks, one ram, seven lambs of the first year; And their meat offering of flour mingled with oil, three tenth deals unto one bullock, two tenth deals unto one ram, A several tenth deal unto one lamb, throughout the seven lambs; And one kid of the goats, to make an atonement for you. Ye shall offer them beside the continual burnt offering, and his meat offering, (they shall be unto you without blemish) and their drink offerings.

Seven weeks shalt thou number unto thee: begin to number the seven weeks from such time as thou beginnest to put the sickle to the corn. And thou shalt keep the feast of weeks unto the LORD thy God with a tribute of a freewill offering of thine hand, which thou shalt give unto the LORD thy God, according as the LORD thy God hath blessed thee: And thou shalt rejoice before the LORD thy God, thou, and thy son, and thy daughter, and thy manservant, and thy maidservant, and the Levite that is within thy gates, and the stranger, and the fatherless, and the widow, that are among you, in the place which the LORD thy God hath chosen to place his name there. And thou shalt remember that thou wast a bondman in Egypt: and thou shalt observe and do these statutes.

For Paul had determined to sail by Ephesus, because he would not spend the time in Asia: for he hasted, if it were possible for him, to be at Jerusalem the day of Pentecost.
