Peter Ackroyd notes that the poem of Isaiah 12 uses the noun yeshuah three times (vv. 2-3). This is especially significant when we consider the distribution of the yasha root in Isaiah, which is “entirely absent from i-xii apart from xii 2-3 and the prophet’s name.”

Isaiah 1 begins by attributing the vision to yeshayahu ; the first section of the book ends with an assurance that Yahweh saves.
