Exodus 23:14-17

DouayRheims(i) 14 Three times every year you shall celebrate feasts to me. 15 Thou shalt keep the feast of unleavened bread. Seven days shalt thou eat unleavened bread, as I commanded thee, in the time of the month of new corn, when thou didst come forth out of Egypt: thou shalt not appear empty before me. 16 And the feast of the harvest of the firstfruits of thy work, whatsoever thou hast sown in the field. The feast also in the end of the year, when thou hast gathered in all thy corn out of the field. 17 Thrice a year shall all thy males appear before the Lord thy God.
