What does the Bible say about flies?

Bible Topic · WEB

The Bible presents flies as instruments of God’s judgment and as a vivid picture of how small corruption can spoil what is good. In Exodus 8:21-31, swarms of flies afflicted Egypt while God distinguished His people, displaying His sovereign power and calling Pharaoh to submit. Psalms 78:45 and 105:31 remember this plague as part of the Lord’s righteous acts against Egypt. Isaiah 7:18 uses flies to portray foreign nations summoned by God to bring judgment. Ecclesiastes 10:1 gives the enduring moral lesson: as dead flies spoil perfume, a little folly can damage a person’s wisdom and honor. Christians therefore should fear God, resist sin, and seek the preserving grace of Christ.
