And the Lord your God, he shall expel them. Or, Jehovah your God, He shall thrust them out. Joshua here uses the unusual word found in Deuteronomy 6:19; Deuteronomy 9:4, another instance of quotation from Deuteronomy.
The word occurs in the sense of thrust in Numbers 35:20, Numbers 35:22. From out of your sight. Rather, from before you.
