The Hebrew word for pestilence can also mean “poisoned arrows”.
I can’t help but think the “poisoned arrows” are those doubtful thoughts “shot” into our head causing us to doubt what the Word of God says.
Jesus praying right before He begins the long night of His passion,
“I am not asking that You remove them from the world,
But I ask that You guard their hearts from evil,
For they no longer belong to this world any more than I do.
Your Word is truth!
John 17:15 & 16 The Passion Translation
