13 And many people came to Jerusalem to keep the Feast of Unleavened Bread in the second month, a very great assembly.
14 They rose up and took away the altars [to idols] that were in Jerusalem, and all the altars and utensils for incense [to the gods] they took away and threw into the Kidron Valley [dumping place for the ashes of such abominations].
15 Then they killed the Passover lamb on the fourteenth day of the second month. And the priests and the Levites were ashamed and sanctified themselves and brought burnt offerings to the Lord's house.
16 They stood in their accustomed places, as directed in the Law of Moses the man of God. The priests threw [against the altar] the blood they received from the hand of the Levites.
17 For many were in the assembly who had not sanctified themselves [become clean and free from all sin]. So the Levites had to kill the Passover lambs for all who were not clean, in order to make them holy to the Lord.
18 For a multitude of the people, many from Ephraim, Manasseh, Issachar, and Zebulun, had not cleansed themselves, yet they ate the Passover otherwise than Moses directed. For Hezekiah had prayed for them, saying, May the good Lord pardon everyone
19 Who sets his heart to seek and yearn for God–the Lord, the God of his fathers–even though not complying with the purification regulations of the sanctuary.
