Exodus:23:28-30
nkjv@Exodus:23:28 @ And I will send hornets before you, which shall drive out the Hivite, the Canaanite, and the Hittite from before you.
nkjv@Exodus:23:29 @ I will not drive them out from before you in one year, lest the land become desolate and the beasts of the field become too numerous for you.
nkjv@Exodus:23:30 @ Little by little I will drive them out from before you, until you have increased, and you inherit the land.
