My ex-husband said that Exodus 23:29-30 supports it but I’m not sure: " 29 But I will not drive them out in a single year, because the land would become desolate and the wild animals would multiply and threaten you. 30 I will drive them out a little at a time until your population has increased enough to take possession of the land."
Exodus 23:29 - 30
ESV - 29 I will not drive them out from before you in one year, lest the land become desolate and the wild beasts multiply against you. 30 Little by little I will drive them out from before you, until you have increased and possess the land.
