Exodus 34:21-23 Common English Bible (CEB)
21 You should do your work for six days, but on the seventh day you should rest. Even during plowing or harvesttime you should rest. 22 You should observe the Festival of Weeks, for the early produce of the wheat harvest, and the Gathering Festival at the end of the year. 23 All your males should appear three times a year before the Lord God, Israel’s God.
