Deuteronomy 8:3

Not in bread alone, &c. i.e. That God is able to make food of what he pleases for the support of man. (Challoner) --- Obedience to his law will insure a happy life, ver. 1. God can support a person's life without any sustenance, as he did Moses, Elias, &c., for a long time. When the usual food is wanting, he can send some of a supernatural kind, as he did the manna. --- Word. Hebrew, "by whatever proceedeth," &c. The Septuagint and our Saviour (Matthew iv. 4,) cite it, however, agreeably to the Vulgate. The word of God and Jesus Christ nourish our souls. (St. Chrysostom) --- Philo says, "God feeds us with his most universal word...which is more ancient than the creation." (Calmet) --- God could make the most poisonous things afford more nutrition, if he commanded us to eat them, than even the most delicious viands. (Abulensis) (Tirinus) --- God can make food of whatever He pleases, or sustain men without meat. (Worthington)
