And it shall be for a sign and for a witness to the LORD of hosts in the land of Egypt…
Even if the language of this verse by itself might seem to point to a particular deliverer, the comprehensive language of the context would forbid its reference to any such exclusively. If the chapter is a prophecy not of a single went but of a great progressive change to be wrought in the condition of Egypt by the introduction of the true religion, the promise of the verse before us must be, that when they cried God would send them a deliverer, a promise verified not once but often, not by Ptolemy or Alexander only, but by others, and in the highest sense by Christ Himself.
(J. A. Alexander.)
