Isaiah 46:4

He found [Jacob] in a desert land, and in the waste howling wilderness; he led him about, he instructed him, he kept him as the apple of his eye.

As an eagle stirreth up her nest, fluttereth over her young, spreadeth abroad her wings, taketh them, beareth them on her wings: so the Lord alone did lead him.

The year is very old, and here is a promise for our aged friends; yes, and for us all, as age creeps over us. Let us live long enough, and we shall all have hoar hairs; therefore we may as well enjoy this promise by the foresight of faith.

When we grow old our God will still be the I AM, abiding evermore the same. Hoar hairs tell of our decay, but He decayeth not. When we cannot carry a burden and can hardly carry ourselves, the Lord will carry us. Even as in our young days He carried us like lambs in His bosom, so will He in our years of infirmity.

Thus saith the Lord that created thee, O Jacob, and he that formed thee, O Israel, Fear not: for I have redeemed thee, I have called thee by thy name; thou art mine.

When thou passest through the waters, I will be with thee; and through the rivers, they shall not overflow thee.—Even to your old age I am he; and even to hoar hairs will I carry you.

I bare you on eagles' wings, and brought you unto myself.—In his love and in his pity he redeemed them; and he bare them, and carried them all the days of old.—As an eagle stirreth up her nest, fluttereth over her young, spreadeth abroad her wings, taketh them, beareth them on her wings: so the Lord alone did lead him.

Even to your old age I am he; and even to hoar hairs will I carry you: I have made, and I will bear; even I will carry, and will deliver you.—This God is our God for ever and ever: he will be our guide even unto death.
