Exodus 23
14 Ref `Three times thou dost keep a feast to Me in a year;
15 Ref 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 Ref 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 Ref `Three times in a year do all thy males appear before the face of the Lord Jehovah.
