Fly.
1. arob, the dog-fly. In Psalms 78:45, and Psalms 105:31, this word is rendered in the A.V. 'divers sorts of flies,' referring to one of the plagues in Egypt, and is translated 'swarms [of flies]' in Exodus 8:21-31: so that more than one kind may have been meant.
2. zebub, supposed to be the gad-fly. They fell into the ointment and spoilt it. Ecclesiastes 10:1. In the judgements of God in the days of Ahaz He hissed for the fly from the rivers of Egypt. Isaiah 7:18. The stings of the flies in the East are very painful, and torment the animals almost to madness. The word zebub is considered to be a part of the word BAAL-ZEBUB, the idol-god of Ekron, 'the lord of the fly,' who it was thought could protect persons from its bite.
