Exodus 23:16-18

Darby Translation

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.

¹⁸ Thou shalt not offer the blood of my sacrifice with leavened bread; neither shall the fat of my feast remain all night until the morning.
