The first; I who am the first, as I said before, Isaiah 41:4, and therefore capable of declaring or foretelling things to come from the beginning, which your idols cannot do, Isaiah 41:26. Shall say to Zion; do and will foretell unto my people by my prophets things to come. Behold, behold them; I represent things future as if they were present, and to be beheld with your eyes. By them he means either,
1. These things which are to come: or,
2. These men; either Cyrus and his forces, who came to deliver the Jews out of Babylon; or, which is the same thing in effect, the Jews returning from their captivity in Babylon. One that bringeth good tidings; a messenger or messengers, the singular number being here put for the plural, as it is in many other places, to wit, my prophets, who shall foretell the good tidings of their deliverance from captivity.
