Exodus 23:16-18

Complete Jewish Bible

¹⁶ Next, the festival of harvest, the firstfruits of your efforts sowing in the field; and last, the festival of ingathering, at the end of the year, when you gather in from the fields the results of your efforts. ¹⁷ Three times a year all your men are to appear before the Lord, Adonai.

¹⁸ “You are not to offer the blood of my sacrifice with leavened bread, nor is the fat of my festival to remain all night until morning.
