Exodus 23:14-17

BBE(i) 14 Three times in the year you are to keep a feast to me. 15 You are to keep the feast of unleavened bread; for seven days let your bread be without leaven, as I gave you orders, at the regular time in the month Abib for in it you came out of Egypt; and let no one come before me without an offering: 16 And the feast of the grain-cutting, the first-fruits of your planted fields: and the feast at the start of the year, when you have got in all the fruit from your fields. 17 Three times in the year let all your males come before the Lord God.
