2 Chronicles 30:1-3

Young's Literal Translation

30 And Hezekiah sendeth unto all Israel and Judah, and also letters he hath written unto Ephraim and Manasseh, to come in to the house of Jehovah in Jerusalem, to make a passover to Jehovah, God of Israel.

² And the king taketh counsel, and his heads, and all the assembly in Jerusalem, to make the passover in the second month,

³ for they have not been able to make it at that time, for the priests have not sanctified themselves sufficiently, and the people have not been gathered to Jerusalem.
