Deuteronomy 16:2, 6, 16

Sacrifice as the Passover to the LORD your God an animal from your flock or herd at the place the LORD will choose as a dwelling for his Name.

except in the place he will choose as a dwelling for his Name. There you must sacrifice the Passover in the evening, when the sun goes down, on the anniversary of your departure from Egypt.

Three times a year all your men must appear before the LORD your God at the place he will choose: at the Festival of Unleavened Bread, the Festival of Weeks and the Festival of Tabernacles. No one should appear before the LORD empty-handed
