'Ceremony' in the Bible

When you enter the land that the Lord will give to you, just as he said, you must observe this ceremony.

When your children ask you, 'What does this ceremony mean to you?' --

When the Lord brings you to the land of the Canaanites, Hittites, Amorites, Hivites, and Jebusites, which he swore to your fathers to give you, a land flowing with milk and honey, then you will keep this ceremony in this month.

All the people, rulers, leaders, and judges were standing on either side of the ark, in front of the Levitical priests who carried the ark of the covenant of the Lord. Both resident foreigners and native Israelites were there. Half the people stood in front of Mount Gerizim and the other half in front of Mount Ebal, as Moses the Lord's servant had previously instructed to them to do for the formal blessing ceremony.
