So they let the decree stand, {to make a proclamation} throughout all Israel, from Beersheba to Dan, to come to make a Passover feast to Yahweh the God of Israel.

And prepare yourselves according to {your families}, according to your working groups, according to the decree of David king of Israel and according to the decree of Solomon his son.

And the singers, the descendants of Asaph, [were] at their stations according to the decree of David and Asaph and Heman and Jeduthun, the seer of the king. And the gatekeepers [were] at {each gate}. They did not need to depart from their service, for their brothers the Levites had made preparations for them.
