Exodus 23:14-17

LXX2012(i) 14 Keep you⌃ a feast to me three times in the year. 15 Take heed to keep the feast of unleavened bread: seven days you⌃ shall eat unleavened bread, as I charged you at the season of the month of new [corn], for in it you came out of Egypt: you shall not appear before me empty. 16 And you shall keep the feast of the harvest of first fruits of your labors, whatever you shall have sown in your field, and the feast of completion at the end of the year in the gathering in of your fruits out of your field. 17 Three times in the year shall all your males appear before the Lord your God.
