The Sudden Attack (vv. 1-2). The phrase “rose up” gives the image of a sudden ambush, a sneak attack that might have defeated Israel, except the Lord was on their side. “If God is for us, who can be against us?” (Rom. 8:31 nkjv; Ps. 56:9; 118:6; Gen. 31:42). Our enemy Satan does not give advance warning of his attacks; therefore, we must be sober and vigilant (1 Peter 5:8), put on the whole armor of God (Eph. 6:10-18), and be alert in our praying. God promised His chosen people that He would curse those who cursed them (Gen. 12:3), and He has kept that promise. The invading armies, such as Assyria and Babylon, did not conquer the Jews because their armies were too great for God, but because God’s people were great sinners and the Lord had to chasten them. If we are walking with the Lord, we need not feel unprepared for the enemy’s sudden attacks.
