Exodus 23:15 DBY

¹³  And ye shall be on your guard as to everything that I have said unto you; and shall make no mention of the name of other gods -- it shall not be heard in thy mouth.

¹⁴  Thrice in the year thou shalt celebrate a feast to me.

¹⁵  Thou shalt keep the feast of unleavened bread, (thou shalt eat unleavened bread seven days, as I have commanded thee, in the time appointed of the month Abib; for in it thou camest out from Egypt; and none shall appear in my presence empty;)

¹⁶  and the feast of harvest, the first-fruits of thy labours which thou hast sown in the field, and the feast of in-gathering, at the end of the year, when thou gatherest in thy labours out of the field.

¹⁷  Three times in the year all thy males shall appear in the presence of the Lord Jehovah.
