Moses
Leviticus 26:36ESV·traditional attribution

And as for those of you who are left, I will send faintness into their hearts in the lands of their enemies. The sound of a driven leaf shall put them to flight, and they shall flee as one flees from the sword, and they shall fall when none pursues.

Matthew Henry Presbyterian @wholebiblehenry

After God had set the blessing before them (the life and good which would make them a happy people if they would be obedient), he here sets the curse before them, the death and evil which would make them as miserable if they were disobedient.

And they shall fall one upon another,.... In their hurry and confusion, everyone making all the haste he can to escape the imaginary danger; or "a man upon his brother" (z); his friend, as Aben Ezra interprets it, having no regard to relation and friendship, every one endeavouring to save himself.

A CURSE TO THE DISOBEDIENT. (Lev. 26:14-39) But if ye will not hearken unto me, &c.--In proportion to the great and manifold privileges bestowed upon the Israelites would be the extent of their national criminality and the severity of their national punishments if they disobeyed.
