Sometimes we are the problem. We weep over the consequences of our actions, or inaction. The truth is we are spiritually defiant or immature when we do this. Our hearts are not completely serving the LORD.
Jdg 2:1 And an angel of the LORD came up from Gilgal to Bochim, and said, I made you to go up out of Egypt, and have brought you unto the land which I sware unto your fathers; and I said, I will never break my covenant with you.
Jdg 2:2 And ye shall make no league with the inhabitants of this land; ye shall throw down their altars: but ye have not obeyed my voice: why have ye done this?
Jdg 2:3 Wherefore I also said, I will not drive them out from before you; but they shall be as thorns in your sides, and their gods shall be a snare unto you.
Jdg 2:4 And it came to pass, when the angel of the LORD spake these words unto all the children of Israel, that the people lifted up their voice, and wept.
Jdg 2:5 And they called the name of that place Bochim (weeping): and they sacrificed there unto the LORD.
Jdg 2:6 And when Joshua had let the people go, the children of Israel went every man unto his inheritance to possess the land.
They wept when they heard the message, but they did not repent.
It is believed that the messenger, the angel of the LORD was an appearance of Jesus in some form as a glorified person before he came to Bethlehem in flesh and blood. He assured them that He would keep his covenant with them which meant the inheritance of the land, blessings for obedience and hardship for disobedience. The inhabitants of the land were not removed so they would be thorns in the side of Israel.
After world war two the people who were the victors settled down, coming out of the memories of the depression and war. they found jobs, they built homes and families, but for many the focus was on enjoying the abundance of things. Japan looked upon America to see what their God was and concluded that it was materialism. Israel had just finished a war with victory, but they had failed for lack of will to complete the job. They were going in to inhabit the land. To enjoy the abundance of things in the new land, no more manna, but an abundance of food. Their hearts were more on the material things than on the spiritual. They would pay the price of intermixing with the people and gods of the land."...they shall be as thorns in your sides, and their gods shall be a snare unto you."
Eventually their land would be overrun by Babylon and the people carried away captive because they were serving other gods. What will become of our nation?
