Exodus 23:15-17

Darby Translation

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.
