Over the millennia, people have tended to take other peoples from their lands, with the most diverse excuses possible. And every time this happens the suffering for populations is extreme. I believe that God puts people to see if they don't do the same thing they wouldn't want done to them. In the book of Matthew chapter 7, verse 12, we have: Therefore, whatever you want men to do to you, do you also, for this is the law and the prophets. Thus, if a people did not like being displaced from their land, they should not displace another people either. But on the day of reckoning, they will be asked whether such people would have liked to be taken from their land, and asked why they took other people from their land. It's interesting how God set David up to condemn himself. We can see this in the second book of Samuel, chapter 12, verses 3 to 6. But the poor man had nothing but a little ewe lamb, which he had bought and raised; and she had grown up with him and his children alike; He ate from her mouthful, and drank from her cup, and slept on her lap, and had her as his daughter. When a traveler came to the rich man, he did not want to take some of his sheep and cattle to feed the traveler who had come to him; but he took the poor man's lamb and prepared it for the man who had come to him. Then David's wrath was greatly kindled against the man, and he said to Nathan, As the Lord lives, the man who did this is worthy of death. And for the lamb he will make restitution four times over, because he did this thing and because he had no mercy. Then Nathan said to David, You are that man! This is what the Lord, the God of Israel, says: I have anointed him king of Israel, and I have delivered him out of the hand of Saul. Notice that in the way David judged others, he was judged. Thus, if a people did not like being taken from their land, they will have to be judged, if they did not take other people from their land.
