Now that we know all the laws, it's time to get down to business.
The Israelites should choose twelve stones from the Jordan, write all of the laws on them, use them to create an altar on Mt. Ebal, and offer sacrifices there. One stone for each tribe.
Six tribes will stand on Mt. Gerizim for the blessing of the people, and six will stand on Mt. Ebal for the curses. That's going to be one symmetrical group photo.
And how about a few curses for good measure? Curses to those who make idols, dishonor their parents, fail to help the needy, engage in improper relationships, or mislead a blind person on the road. Good list.
