Man being made out of the earth, his Maker has wisely ordered him food out of the earth, Psalms 104:14. But the people of Israel typifying the church of the firstborn that are written in heaven, receiving their charters, laws, and commissions from heaven; from heaven also they received their food. See what God designed in making this provision for them; that I may prove them, whether they will walk in my law or no Whether they would trust and serve him, and be ever faithful to so good a master.
