These are the places where the ancient Aramaic-language translation and creative amplification (Targum Jonathan) of the Hebrew-language book of Isaiah makes explicit mention of the promised and long-awaited Messiah.
It's interesting to see the ancient understanding of Isaiah's prophecies dating from c.150 BCE – c.350 CE, and to note the places where Jonathan Ben Uzziel inserts in “the Messiah” in places where the original Hebrew text made no explicit mention of the Messiah using that word. This also reveals to us various Messianic titles present in the Hebrew text, that aren't always obvious at first.

The prophet said to the house of David, For unto us a child is born, unto us a son is given, and he has taken the law upon himself to keep it.
