A lattice - The “upper chamber” had probably 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 - literally, “Lord (i. e., averter) of flies.” Flies in the East constitute one of the most terrible of plages Psalms 105:31; Exodus 8:24; and Orientals would be as likely to have a “god of flies” as a god of storm fand thunder. To inquire 2 Kings 1:3 of Baal-zebub 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.
