The consensus of scholars is that the Book of Isaiah can be divided into three distinct sections, which were probably originally three separate books.
- Chapters 1 to 39 were written during the late eighth and early
seventh centuries BCE by Isaiah, son of Amoz, apart from numerous
additions from a later period. For ease of reference, Isaiah is
often referred to as First Isaiah, or proto-Isaiah.
- Chapters 40 to 55 were written by a prophet living in exile during
the latter part of the Babylonian Exile. This author is referred to
as Second Isaiah or Deutero-Isaiah.
- A third source, now known as Third Isaiah, or Trito-Isaiah, wrote
chapters 56 to 66 during the period following the Return from Exile. This chapter, chapter 63 was therefore written after the Return from Exile.
In this chapter, the author reminisces on the history of Israel; how God led the people in good times and punished them when they strayed. Isaiah 63:17-18 says:
17 Why do you let us wander, O LORD, from your ways, and harden our hearts so that we fear you not? Return for the sake of your servants, the tribes of your heritage.
18 Why have the wicked invaded your holy place, why have our enemies trampled your sanctuary?
The references to 'holy place' and 'sanctuary' in verse 18 are to the Babylonian destruction of the temple in Jerusalem. This is not at all about limits to free will, but seeking answers why God lets the Jews stray, only to punish them. If anything, Third Isaiah is regretting that the Jews have too much free will.
