You must revere the LORD your God: only Him shall you worship, to Him shall you hold fast, and by His name shall you swear.
Deuteronomy 10:20
If, then, you faithfully keep all this Instruction that I command you, loving the LORD your God, walking in all His ways, and holding fast to Him, the LORD will dislodge before you all these nations: you will dispossess nations greater and more numerous than you.
Deuteronomy 11:22-23
