TSK · Deuteronomy 16:13

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 on the fifteenth day of the seventh month ye shall have an holy convocation; ye shall do no servile work, and ye shall keep a feast unto the LORD seven days:

Wherefore all the men of Israel assembled themselves unto the king in the feast which [was] in the seventh month.

Even after a certain rate every day, offering according to the commandment of Moses, on the sabbaths, and on the new moons, and on the solemn feasts, three times in the year, [even] in the feast of unleavened bread, and in the feast of weeks, and in the feast of tabernacles.

And they found written in the law which the LORD had commanded by Moses, that the children of Israel should dwell in booths in the feast of the seventh month:

Now the Jews' feast of tabernacles was at hand.
