20 That thou mayest love the LORD thy God, and that thou mayest obey his voice, and that thou mayest cleave unto him: for he is thy life, and the length of thy days: that thou mayest dwell in the land which the LORD sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give them.
*To love God, obey his words, and stay close to him because he gives you life and long days. This way, you can live in the land that God promised to your ancestors, Abraham, Isaac, and Jacob.
