What does 2 Chronicles 31:1 mean?

Now when all this was finished, all Israel that were present went out to the cities of Judah, and brake in pieces the pillars, and hewed down the Asherim, and brake down the high places and the altars out of all Judah and Benjamin, in Ephraim also and Manasseh, until they had destroyed them all. Then all the children of Israel returned, every man to his possession, into their own cities.

Now when all this was finished, all Israel that were present went out to the cities of Judah, and brake the images in pieces, and cut down the groves, and threw down the high places and the altars out of all Judah and Benjamin, in Ephraim also and Manasseh, until they had utterly destroyed them all. Then all the children of Israel returned, every man to his possession, into their own cities.

Now when all this was finished, all Israel that were present went out to the cities of Judah, and brake in pieces the pillars, and hewed down the Asherim, and brake down the high places and the altars out of all Judah and Benjamin, in Ephraim also and Manasseh, until they had destroyed them all. Then all the children of Israel returned, every man to his possession, into their own cities.

Now when all this was over, all the men of Israel who were present went out into the towns of Judah, causing the stone pillars to be broken up and the wood pillars to be cut down, pulling down the high places and the altars in all Judah and Benjamin, as well as in Ephraim and Manasseh, till all were gone. Then all the children of Israel went back to their towns, every man to his property.

And at the completion of all this, gone out have all Israel who are found present to the cities of Judah, and break the standing-pillars, and cut down the shrines, and break down the high places and the altars, out of all Judah and Benjamin, and in Ephraim and Manasseh, even to completion, and all the sons of Israel turn back, each to his Possession, to their cities.

And when these things had been duly celebrated, all Israel that were found in the cities of Juda, went out, and they broke the idols, and cut down the groves, demolished the high places, and destroyed the altars, not only out of all Juda and Benjamin, but out of Ephraim also and Manasses, till they had utterly destroyed them: then all the children of Israel returned to their possessions and cities.

And when all this was finished, all Israel that were present went out to the cities of Judah, and broke the columns, and hewed down the Asherahs, and demolished the high places and the altars in all Judah and Benjamin, in Ephraim also and Manasseh, until they had destroyed them all. And all the children of Israel returned every man to his possession, into their cities.
