Deuteronomy 16:16 NIrV

[16] All your men must appear in front of the LORD your God at the holy tent. They must go to the place he will choose. They must do it three times a year. They must go there to celebrate the Feast of Unleavened Bread, the Feast of Weeks and the Feast of Booths. None of your men should appear in front of the LORD without bringing something with him.
