Early the next morning King Hezekiah gathered the city officials together and went up to the temple of the LORD.
They brought seven bulls, seven rams, seven male lambs and seven male goats as a sin offeringa for the kingdom, for the sanctuary and for Judah. The king commanded the priests, the descendants of Aaron, to offer these on the altar of the LORD.
Or "purification offering" ; also in verses 23 and 24
So they slaughtered the bulls, and the priests took the blood and splashed it against the altar; next they slaughtered the rams and splashed their blood against the altar; then they slaughtered the lambs and splashed their blood against the altar.
The priests then slaughtered the goats and presented their blood on the altar for a sin offering to atone for all Israel, because the king had ordered the burnt offering and the sin offering for all Israel.
He stationed the Levites in the temple of the LORD with cymbals, harps and lyres in the way prescribed by David and Gad the king’s seer and Nathan the prophet; this was commanded by the LORD through his prophets.
