And Hezekiah the king rose early and gathered the lords of the city and went up to the house of the LORD. read more.
And there were brought seven oxen, seven rams, seven lambs and seven kids to be a sin offering for the kingdom, for the sanctuary and for Judah. And he commanded the priests the sons of Aaron to offer them on the altar of the LORD. And they slew the oxen; and the priests received the blood and sprinkled it on the altar; and they slew the rams and sprinkled the blood upon the altar; and they slew the lambs and sprinkled the blood upon the altar. And then they brought forth the kids of the sin offering before the king and the congregation which put their hands upon them. And the priests slew them and offered the blood of them upon the altar, to make satisfaction for all Israel, for the king said that the burnt offering and the sin offering should serve for all Israel.
