Philistia may take refuge in Zion (Isaiah 14:32b)

In this chapter, 14:28 is identified as the original introduction to a series of early oracles against the nations in the book and the original poem against Philistia consisted of vv 29, 31-32a plus an ending which is now lost to us. This poem spoke of a future Assyrian attack on the Philistine cities and is to be dated in the pre-exilic period. Verse 30b was written against ‘the rod’ sometime during the exilic period. Verse 32b was then written in the late-exilic period primarily to assert YHWH’s establishment of Zion as a place of refuge for his people in exile. By setting v 32b as an answer to the Philistine messengers, the invitation to hide in Zion is extended to the Philistines too. The use of language in v 32b finds close parallels in chs 40-55 (49:13 in particular).
