God promises to bless Israel if they obey Him and His commandments. He will bless Israel with victory over other nations, children, cattle, crops, rain, and being above other nations. However, if they disobey God and His commandments, God promises to curse them by doing the opposite - being defeated by other nations, giving away their children, not being able to eat their cattle, little crops, little rain, and other nations being above them. So, the main takeaway is to fear God, love God’s commandments, and respond in obedience to God.
