And shall say, Cast you up, cast you up, prepare the way, take up the stumbling block out of the way of my people.
In this passage the cry goes forth, not on behalf of a conqueror, or a sovereign, but on behalf of God's people. They are the honoured procession for which a road is to be prepared. "Cast up, cast up" — that is, heap up, fill in, "prepare the way, take up the stumbling-block out of the way of My people." The figure, then, is striking. As royalty demanded for itself a smooth path, a road from which all dangers and obstructions were taken away, so a soul that is on its way to God has thrown over it, as it were, something of the sovereignty which it approaches, and a mysterious voice is heard, crying, "Clear the way I heap up! heap up! cast out the stumbling-stones."
(H. W. Beecher.)
