46:1-4 The heathen insulted the Jews, as if their idols Bel and Nebo were too hard for Jehovah. But their worshippers cannot help them; both the idols and the idolaters are gone into captivity. Let not God's people be afraid of either. Those things from which ungodly men expect safety and happiness, will be found unable to save them from death and hell. The true God will never fail his worshippers. The history of the life of every believer is a kind of abstract of the history of Israel. Our spiritual life is upheld by his grace, as constantly as our natural life by his providence. And God will never leave them. The Author will be the Finisher of their well-being, when, by decays, they need help as much as in infancy. This promise to Israel, enfeebled and grown old as a nation, is applicable to every aged follower of Christ. When compassed about with infirmities, and perhaps those around begin to grow weary of you, yet I am He that I have promised to be, He that you would have me to be. I will bear you up; carry you on in your way, and carry you home at last. If we learn to trust in and love him, we need not be anxious about our remaining days or years; he will still provide for us and watch over us, both as the creatures of his power, and as new-created by his Spirit.

3. in contrast to what precedes: Babylon's idols, so far from bearing its people safely are themselves borne off, a burden to the laden beast; but Jehovah bears His people in safety even from the womb to old age (Isa 63:9; De 32:11; Ps 71:6, 18). God compares Himself to a nurse tenderly carrying a child; contrast Moses' language (Nu 11:12).
