It’s amazing how Deuteronomy affects the rest of the Old Testament.
For if you will be careful to do all this commandment that I command you to do, loving the Lord your God, walking in all his ways, and holding fast to him, then the Lord will drive out all these nations before you, and you will dispossess nations greater and mightier than yourselves. Every place on which the sole of your foot treads shall be yours. Your territory shall be from the wilderness to the Lebanon and from the River, the river Euphrates, to the western sea. No one shall be able to stand against you. The Lord your God will lay the fear of you and the dread of you on all the land that you shall tread, as he promised you.
And then the book of Joshua uses the term ‘foot’ to show what God is doing in giving them the land.
Deuteronomy 7:17-24 “If you say in your heart, ‘These nations are greater than I. How can I dispossess them?’ you shall not be afraid of them but you shall remember what the Lord your God did to Pharaoh and to all Egypt, the great trials that your eyes saw, the signs, the wonders, the mighty hand, and the outstretched arm, by which the Lord your God brought you out. So will the Lord your God do to all the peoples of whom you are afraid. Moreover, the Lord your God will send hornets among them, until those who are left and hide themselves from you are destroyed. You shall not be in dread of them, for the Lord your God is in your midst, a great and awesome God. The Lord your God will clear away these nations before you little by little. You may not make an end of them at once, lest the wild beasts grow too numerous for you. But the Lord your God will give them over to you and throw them into great confusion, until they are destroyed. And he will give their kings into your hand, and you shall make their name perish from under heaven. No one shall be able to stand against you until you have destroyed them.
And then the book of Judges emphasizes the term ‘hand’ to show what God is doing in delivering them from their enemies.
