In that day...

As seen by Isaiah and perhaps others.

It's time to look at this phrase in particular as presented in various contexts starting with Isiah and continuing as times and circumstances permit. This is a side effort in patiently believing while watching the words of God as spoken through the prophets unfold. I will be discussing each context with minimal elaboration and providing a 'score' for each to relate relevance to the contents of the presentation. The score will be 0-5 stars with zero being represented by a -.

What does 'day' mean? It has been speculated that a day can refer to a 1000 years. (Psalm 90:4, 2 Peter 3:8) This is interesting in that following the biblical timeline since the creation of man, the sixth day is approaching an end. Is that what is meant when Isaiah and others say, "in that day?" No speculation one way or the other as what is sufficient I expect for this discussion is in general, we will find, that day often points to our time, now.

Isaiah 4 : ***** (5)
This context has been referenced multiple times and thus must receive the highest score. The phrase in focus is specifically used twice and "it shall come to pass" adds to it.
The first occurrents is later mirrored by the Angels in John's Revelation. The chapters of interest there are 17 and 18:

In the measure that she glorified herself and lived luxuriously, in the same measure give her torment and sorrow; for she says in her heart, ‘I sit as queen, and am no widow, and will not see sorrow.’ Therefore her plagues will come in one day—death and mourning and famine. And she will be utterly burned with fire, for strong is the Lord God who judges her. Rev 18:7-8
(Verse 8 is included to reflect the gravity of what is being stated.)

Isaiah continues: also in that day, it will be beautiful for those who have escaped. Then, also, it shall come to pass that those who remain in Zion and Jerusalem will be called Holy. Judgement will come, but protection and guidance will be provided. (Isa 4:4-6)

It is interpreted here that this verse does in fact reference the end times through the correlation with Jobn's Revelation which begins with the messages to the seven churches. It is then thus inferred that Zion and Jerusalem do not reference boundaries over earth but boundaries of association - those who have remained true to the Lord and have accepted and follow His plans for them.

In general, the theme presented in this context proves to be again familiar.

Isaiah made his proclamations to a divided kingdom prior to the Assyrians capturing the northern kingdom of Judah. Thomas Nelson says, "The record of Isaiah's visions contains the revelations that God gave during the reigns of Uzziah, Hotham, Ahaz, and Hezekiah. God never changes, and this revelation is still relevant for His people today."
Isaiah is predictive in nature discussing what the Assyrians will do and the consequences for doing so. The Assyrians did not act of their own volition according to Isaiah, but were rather a tool used by God to decimate the sins and offences that engrossed His people. In the text which predates Daniel significantly, Cyrus is specifically mentioned. Naturally, as with Daniel, skepticism abounds concerning the authenticity of this claim. Going forward, the contexts of Isaiah's prophecies must be determined. The Assyrians are the subject of much discussion but are they the subject of exclusive context, shared or repetitive context, or analogous context?
