It says "Manasseh" in most Bibles, but if you will look in your margin it says Moses. The Jews were ashamed that a grandson of Moses would be caught up in something like this and so they changed it.
What bigger name was there in Israel's history than Moses? Do you see why he picked Dan? Do you think Jeroboam was dumb? "Hey, Moses' grandson had set up an altar there. This is a holy place. There isn't any place in the nation, except maybe Bethel, that can even begin to approach, in terms of holiness, in terms of religious value, the city of Dan. Let's set up an altar there too. Doesn't that sound good? After all we need to honor Moses. What greater honor could there be than we establish an altar, a place to make sacrifice? All the time we go there to honor God, we'll also remember Moses as well."
