And he made all the priests from the towns of Judah come into Jerusalem, and he made unclean the high places where the priests had been burning offerings, from Geba to Beer-sheba; and he had the high places of the evil spirits pulled down which were by the doorway of Joshua, the ruler of the town, on the left side of the way into the town.

And as for the people that remained in the land of Judah, whom Nebuchadnezzar king of Babylon had left, even over them he made Gedaliah the son of Ahikam, the son of Shaphan, ruler.
