Exodus 23:14-17

ACV(i) 14 Three times thou shall keep a feast to me in the year. 15 Thou shall keep the feast of unleavened bread (Seven days thou shall eat unleavened bread, as I commanded thee, at the time appointed in the month Abib, for in it thou came out from Egypt, and none shall appear before me empty), 16 and the feast of harvest, the first-fruits of thy labors, which thou sow in the field, and the feast of ingathering at the end of the year, when thou gather in thy labors out of the field. 17 Three times in the year all thy males shall appear before lord LORD.
