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.
Ver. 20. For he is thy life.] He in whom thou livest, as the fish doth in the water, the lamp in the oil, &c. He is the author of life natural, spiritual, and eternal to his obedient servants.
