When the Lord thy God shall have brought thee into the land, which thou art going in to possess, and shall have destroyed many nations before thee, the Hethite, and the Gergezite, and the Amorrhite, and the Chanaanite, and the Pherezite, and the Hevite, and the Jebusite, seven nations much more numerous than thou art, and stronger than thou:
Deuteronomy 7:1 When the Lord thy God shall have brought thee into the land, which thou art going in to possess, and shall have destroyed many nations before thee, the Hethite, and the Gergezite, and the Amorrhite, and the Chanaanite, and the Pherezite, and the Hevite, and the Jebusite, seven nations much more numerous than thou art, and stronger than thou:
Deuteronomy 7:2 And the Lord thy God shall have delivered them to thee, thou shalt utterly destroy them. Thou shalt make no league with them, nor shew mercy to them:
Deuteronomy 7:3 Neither shalt thou make marriages with them. Thou shalt not give thy daughter to his son, nor take his daughter for thy son:
The verse centers on "lord", "shall", "brought", "thee", "land", "thou", "going", and "possess". It is saying that the verse draws attention to "lord" and "shall", so its meaning should be read from those terms before moving to application.
The next verse adds "And the Lord thy God shall have...", so "lord" and "shall" should be read forward into that movement. In Deuteronomy context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "lord" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
