(1.) He gains the victory purely by his own strength: I have trodden the wine-press alone, v. 3. When God delivered his people and destroyed their enemies, if he made use of instruments, he did not need them. But among his people, for whom the salvation was to be wrought, no assistance offered itself; they were weak and helpless, and had no ability to do any thing for their own relief; they were desponding and listless, and had no heart to do any thing; they were not disposed to give the least stroke or struggle for liberty, neither the captives themselves nor any of their friends for them (v. 5): "I looked, and there was none to help, as one would have expected, nothing of a bold active spirit appeared among them; nay, there was not only none to lead, but, which was more strange, there was none to uphold, none that would come in as a second, that had the courage to join with Cyrus against their oppressors; therefore my arm brought about the salvation; not by created might or power, but by the Spirit of the Lord of hosts, my own arm." Note, God can help when all other helpers fail; nay, that is his time to help, and therefore for that very reason he will put forth his own power so much the more gloriously. But this is most fully applicable to Christ's victories over our spiritual enemies, which he obtained by a single combat. He trod the wine-press of his Father's wrath alone, and triumphed over principalities and powers in himself, Col. ii. 15. Of the people there was none with him; for, when he entered the lists with the powers of darkness, all his disciples forsook him and fled. There was non to help, none that could, none that durst; and he might well wonder that among the children of men, whose concern it was, there was not only none to uphold, but that there were so many to oppose and hinder it if they could.
