He built altars for all the host of heaven in the two courtyards of the house of Yahweh

The word "host" is a metaphor for the stars, speaking of them as if they were an army. It is implied that Manasseh built these altars so people could make sacrifices and worship the stars. Also, he would not have built these altars himself, rather he would have commanded his workers to do it. Alternate translation: "He had his workers build altars in the two courtyards of the house of Yahweh so that the people could worship the stars and offer them sacrifices" (See: rc://en/ta/man/jit/figs-explicit and rc://en/ta/man/jit/figs-metonymy)
