We have now reached that point of Isaiah's prophesying at which the Messiah becomes the most conspicuous figure on his horizon. Let us take advantage of it, to gather into one statement all that the prophet told his generation concerning that exalted and mysterious Person.[22] [22] The Messiah, or _Anointed_, is used in the Old Testament of many agents of God: high-priest (Lev. iv. 3); ministers of the Word (Ps. cv. 15); Cyrus (Isa. xlv. 1); but mostly of God's king, actual (1 Sam. xxiv. 7), or expected (Dan. ix. 25). So it became in Jewish theology the technical term for the coming King and the Captain of salvation. When Isaiah began to prophesy, there was current among the people of Judah the expectation of a glorious King. How far the expectation was defined it is impossible to ascertain; but this at least is historically certain. A promise had been made to David (2 Sam. vii. 4-17) by which the permanence of his dynasty was assured. His offspring, it was said, should succeed him, yet eternity was promised not to any individual descendant, but to the dynasty. Prophets earlier than Isaiah emphasized this establishment of the house of David, even in the days of Israel's greatest distress; but they said nothing of a single monarch with whom the fortunes of the house were to be identified. It is clear, however, even without the evidence of the Messianic Psalms, that the hope of such a hero was quick in Israel. Besides the documentary proof of David's own last words (2 Sam. xxiii.), there is the manifest impossibility of dreaming of an ideal kingdom apart from the ideal king. Orientals, and especially Orientals of that period, were incapable of realizing the triumph of an idea or an institution without connecting it with a personality. So that we may be perfectly sure, that when Isaiah began to prophesy the people not only counted upon the continuance of David's dynasty, as they counted upon the presence of Jehovah Himself, but were familiar with the ideal of a monarch, and lived in hope of its realization.
