“Three times a year all your males shall appear before the Lord your God in the place which He chooses, at the Feast of Unleavened Bread (Passover) and at the Feast of Weeks (Pentecost) and at the Feast of Booths (Tabernacles), and they shall not appear before the Lord empty-handed.

For it is not an empty or trivial matter for you; indeed it is your [very] life. By [honoring and obeying] this word you will live long in the land, which you are crossing the Jordan to possess.”
