What does 2 Kings 17:27 mean?

The king of Assyria brought men from Babylon, from Cuthah, from Avva, and from Hamath and Sepharvaim, and placed them in the cities of Samaria instead of the children of Israel; and they possessed Samaria, and lived in its cities.

So it was, at the beginning of their dwelling there, that they didn’t fear Yahweh. Therefore Yahweh sent lions among them, which killed some of them.

Therefore they spoke to the king of Assyria, saying, “The nations which you have carried away and placed in the cities of Samaria don’t know the law of the god of the land. Therefore he has sent lions among them, and behold, they kill them, because they don’t know the law of the god of the land.”

So one of the priests whom they had carried away from Samaria came and lived in Bethel, and taught them how they should fear Yahweh.

However every nation made gods of their own, and put them in the houses of the high places which the Samaritans had made, every nation in their cities in which they lived.

The men of Babylon made Succoth Benoth, and the men of Cuth made Nergal, and the men of Hamath made Ashima,
