Exodus 34:22-24 Common English Bible (CEB)
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. 24 I will drive out nations before you and extend your borders. No one will desire and try to take your land if you go up and appear before the Lord your God three times a year.
