God sent the hornet before them, and drove out the two kings of the Amorites, referring thereby to their defeat and destruction by the Israelites through the miraculous interposition of God, and thus placing the figurative use of the term hornet beyond the possibility of doubt. These hornets, however, which are very aptly described in Wis. 12:8, on the basis of this passage, as προδρόμους, the pioneers of the army of Jehovah, do not denote merely varii generis mala, as Rosenmüller supposes, but acerrimos timoris aculeos, quibus quodammodo volantibus rumoribus pungebantur, ut fugerent (Augustine, quaest. 27 in Jos.). If the fear of God which fell upon the Canaanites threw them into such confusion and helpless despair, that they could not stand before Israel, but turned their backs towards them, the stings of alarm which followed this fear would completely drive them away. Nevertheless God would not drive them away at once, “in one year,” lest the land should become a desert for want of men to cultivate it, and the wild beasts should multiply against Israel; in other words, lest the beasts of prey should gain the upper hand and endanger the lives of man and beast (Lev 26:22; Eze 14:15, Eze 14:21), which actually was the case after the carrying away of the ten tribes (2Ki 17:25-26). He would drive them out by degrees (מעט מעט, only used here and in Deu 7:22), until Israel was sufficiently increased to take possession of the land, i.e., to occupy the whole of the country. This promise was so far fulfilled, according to the books of Joshua and Judges, that after the subjugation of the Canaanites in the south and north of the land, when all the kings who fought against Israel had been smitten and slain and their cities captured, the entire land was divided among the tribes of Israel, in order that they might exterminate the remaining Canaanites, and take possession of those portions of the land that had not yet been conquered (Jos 13:1-7). But the different tribes soon became weary of the task of exterminating the Canaanites, and began to enter into alliance with them, and were led astray by them to the worship of idols; whereupon God punished them by withdrawing His assistance, and they were oppressed and humiliated by the Canaanites because of their apostasy from the Lord (Judg 1 and 2).
