Deuteronomy 7:20 Meaning and Commentary

Deuteronomy 7:20

Moreover, the Lord thy God will send the hornet among them,
&c.] Not a single one, but several of them, and which may be understood of creatures so called, which resemble wasps, only twice as large, an insect very bold and venomous; see ( Exodus 23:28 ) . Aben Ezra interprets it of the leprosy:

until they that are left, and hide themselves from thee, be destroyed;
such of the Canaanites who escaped the sword of the Israelites, and hid themselves in holes and caverns of the earth; these the hornets would find out and sting them to death, until they were all destroyed. Thus God can make use of small creatures, even insects, to destroy nations the most populous and mighty.
