Exodus 23:14-17

YLT(i) 14 `Three times thou dost keep a feast to Me in a year; 15 the Feast of Unleavened things thou dost keep; seven days thou dost eat unleavened things, as I have commanded thee, at the time appointed in the month of Abib; for in it thou hast come forth out of Egypt, and ye do not appear in My presence empty; 16 and the Feast of Harvest, the first fruits of thy works which thou sowest in the field; and the Feast of the In-Gathering, in the outgoing of the year, in thy gathering thy works out of the field. 17 `Three times in a year do all thy males appear before the face of the Lord Jehovah.
