Exodus 23:15 YLT

¹³  and in all that which I have said unto you ye do take heed; and the name of other gods ye do not mention; it is not heard on thy mouth.

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.
