Exodus 23:15-17 Common English Bible (CEB)
15 Observe the Festival of Unleavened Bread, as I commanded you. Eat unleavened bread for seven days at the appointed time in the month of Abib,[a] because it was in that month that you came out of Egypt.
No one should appear before me empty-handed. 16 Observe the Harvest Festival for the early produce of your crops that you planted in the field, and the Gathering Festival at the end of the year, when you gather your crop of fruit from the field. 17 All your males should appear three times a year before the Lord God.
