Adam Clarke on 2 Kings 1:2

Fell down through a lattice - Perhaps either through the flat root of his house, or over or through the balustrades with which the roof was surrounded.

Go, inquire of Baal-zebub - Literally, the fly-god, or master of flies. The Septuagint has βααλ μυιαν, Baal the fly. He was the tutelary god of Ekron, and probably was used at first as a kind of telesm, to drive away flies. He became afterwards a very respectable devil, and was supposed to have great power and influence. In the New Testament Beelzebub is a common name for Satan himself, or the prince of devils. See my notes on Mat 10:25 (note).
