Trust God - not human strength
I led you up from Egypt and brought you to the land of which I swore to your fathers; and I said, ‘I will never break My covenant with you. ‘And you shall make no covenant with the inhabitants of this land; you shall tear down their altars.’ But you have not obeyed My voice. Why have you done this? Therefore... they shall be thorns in your side, and their gods shall be a snare to you.’ ” 1-7
Now Joshua the son of Nun, the servant of the Lord, died... When all that generation had been gathered to their fathers, another generation arose after them who did not know the Lord nor the work which He had done for Israel. 8-11
Then the children of Israel did evil in the sight of the Lord... they forsook the Lord God of their fathers, who had brought them out of the land of Egypt; and they followed other gods from among the gods of the people who were all around them.... So He delivered them into the hands of plunderers who despoiled them; and He sold them into the hands of their enemies all around, so that they could no longer stand before their enemies. Wherever they went out, the hand of the Lord was against them for calamity, as the Lord had said, and as the Lord had sworn to them. And they were greatly distressed. 11-15
Nevertheless, the Lord raised up judges who delivered them out of the hand of those who plundered them. Yet they would not listen to their judges, but they played the harlot with other gods, and bowed down to them. They turned quickly from the way in which their fathers walked, in obeying the commandments of the Lord; they did not do so. And when the Lord raised up judges for them, the Lord was with the judge and delivered them out of the hand of their enemies all the days of the judge; for the Lord was moved to pity by their groaning because of those who oppressed them and harassed them. 16-18
And it came to pass, when the judge was dead, that they reverted and behaved more corruptly than their fathers, by following other gods, to serve them and bow down to them. They did not cease from their own doings nor from their stubborn way.
Then the anger of the Lord was hot against Israel; and He said, “Because this nation has transgressed My covenant which I commanded their fathers, and has not heeded My voice, I also will no longer drive out before them any of the nations which Joshua left when he died, so that through them I may test Israel, whether they will keep the ways of the Lord, to walk in them as their fathers kept them, or not.” 19-22
