Isaiah 7:18-19

Yahweh would summon the armies of Assyria and Egypt to do His bidding as one whistles (or hisses) at insects (cf. Isaiah 5:26). The ancients could evidently control flies and bees by hissing at them. [Note: See Young, 1:296, for sources indicating this in Aeschylus’ writings.] Egypt was a land filled with flies, and the ancients spoke of Assyria as a country of beekeeping. [Note: Ibid.] Enemy soldiers would swarm everywhere in Judah (cf. Judges 6:1-6).
