Deuteronomy 11:30

30.Are they not on the other side of Jordan. Although the form of interrogation is common in Hebrew, yet in this place Moses affirms more vehemently than as if he had only stated directly that these mountains were in the land of Canaan; for he wishes to encourage them in the confidence of entering the promised inheritance; just as he adds immediately afterwards, “Ye shall pass over Jordan.” For, although they had already experienced the miraculous power of God in the conquest of the Amorites, and in heir occupation of the land of Bashan, yet such was their incredulity, that it was necessary constantly to dissipate their fears, so that they might lay aside all hesitation, and boldly prepare to advance. Finally, he founds an exhortation upon this great goodness of God; for the actual enjoyment of the land ought to have stimulated them the more in the service of God, because they were made to inherit it for the purpose of keeping the Law.
