Whoever among the families of the earth doesn't go up to Jerusalem to pay homage to the king, the LORD of heavenly forces, upon them no rain will fall.
And if the family of Egypt doesn't go up and doesn't present itself, then no rain will fall on them. There will be a plague like the one with which the LORD struck the nations that didn't go up to celebrate the Festival of Booths.

On that day, Holy to the LORD will be inscribed on the bells of the horses, and the pots in the LORD's house will be holy like the bowls before the altar.
