Albert Barnes Commentary 2 Kings 1:2

"And Ahaziah fell down through the lattice in his upper chamber that was in Samaria, and was sick: and he sent messengers, and said unto them, Go, inquire of Baal-zebub, the god of Ekron, whether I shall recover of this sickness." — 2 Kings 1:2 (ASV)

A lattice - The “upper chamber” probably had a single latticed window, through which Ahaziah fell. Windows in the East are to this day generally closed by lattices of interlaced wood, which open outward, so that if the fastening is not properly secured, one who leans against them may easily fall out.

Baal-zebub - This name literally means “Lord (that is, averter) of flies.” In the East, flies constitute one of the most terrible of plagues (Psalms 105:31; Exodus 8:24), and people of the Orient would be as likely to have a “god of flies” as a god of storm and thunder. To inquire of Baal-zebub (2 Kings 1:3) was practically to deny Yahweh. Ahaziah cast aside the last remnant of respect for the old religion and consulted a foreign oracle, as if the voice of God were wholly silent in his own country.
