Why has there been so much hatred?...The ultimate and only full explanation must be found in God's words to the serpent in the Garden of Eden, when he said, "I will put enmity between you and the woman, and between your offspring and hers; he will crush your head, and you will strike his heel” (Genesis 3:15). Satan hates the Jews because God promised to send the Messiah through them, which is why he stirred up Pharaoh and his court and why he caused Herod to strike out against the Jewish babies at the time of Christ's birth. 

What is significant about the specific peoples listed in the ongoing flow of the psalm (vv. 6-11) is that they form an almost complete circle of entrapment around Israel...There was no time in Israel's history, so far as we know, when these precise ten powers were actually arrayed against her. So the listing in verses 6-8 is probably a generalization. It is a way of saying that the Jews always seemed to be surrounded by enemies and in danger of being liquidated.

But here is an even greater problem. How about when God does nothing? What should we think when he is silent when his people call to him in trouble? This is no small matter. It is a terrible problem, and it is what Psalm 83 is about. It tells God, “Do not keep silent; be not quiet...be not still” when we are surrounded by our enemies.

Above all, thank God for your many spiritual blessings. We are thankful for our material blessings, or should be. But remember to keep them in perspective. A person may possess much and still perish miserably in the end. This is why Jesus asked the piercing question, “What good will it be for a man if he gains the whole world, yet forfeits his soul” (Matt. 16:26)? As wonderful as our material blessings are, they are still far less important that our spiritual treasures.

There is one more thing this passage adds to our enjoyment of good things that sets the enjoyment of God's people off from that of hedonists. It is the most obvious thing of all: the knowledge that all we have is from God and the heartfelt giving of thanks to him for it. That is why Nehemiah reminded the people that “this day is sacred to our Lord” and that “the joy of the LORD is your strength.”
