Deuteronomy 11:21-23

American Standard Version

²¹ that your days may be multiplied, and the days of your children, in the land which Jehovah sware unto your fathers to give them, as the days of the heavens above the earth. ²² For if ye shall diligently keep all this commandment which I command you, to do it, to love Jehovah your God, to walk in all his ways, and to cleave unto him; ²³ then will Jehovah drive out all these nations from before you, and ye shall dispossess nations greater and mightier than yourselves.
