When the house of David (Judah) was told, “Aram is allied with Ephraim (Israel),” the hearts of Ahaz and his people trembled as the trees of the forest tremble in the wind.

Then Isaiah said, “Hear then, O house of David! Is it too small a thing for you to try the patience of men, but will you try the patience of my God as well?

There shall be no end to the increase of His government and of peace,
[He shall rule] on the throne of David and over his kingdom,
To establish it and to uphold it with justice and righteousness
From that time forward and forevermore.
The zeal of the Lord of hosts will accomplish this.

Then a Shoot (the Messiah) will spring from the stock of Jesse [David’s father],
And a Branch from his roots will bear fruit.

A throne will be established in lovingkindness,
And One will sit on it in faithfulness in the tent (dynasty, family) of David;
Judging and seeking justice
And being prompt to do righteousness.

You saw that the breaches
In the wall of the City of David [the citadel of Zion] were many;
You collected [within the city’s walls] the waters of the Lower Pool (Siloam).

“Then I will set on his shoulder the key of the house of David;
When he opens no one will shut,
When he shuts no one will open.

Woe (judgment is coming) to Ariel, to Ariel, the city where David [once] camped!
Add yet another year; let the feasts run their course [but only one year more].

‘For I will defend this city to save it, for My own sake and for the sake of My servant David.’”

“Go and say to Hezekiah, ‘For the Lord, the God of David your father says this, “I have heard your prayer, I have seen your tears; listen carefully, I will add fifteen years to your life.

“Incline your ear [to listen] and come to Me;
Hear, so that your soul may live;
And I will make an everlasting covenant with you,
According to the faithful mercies [promised and] shown to David.

“Listen carefully, I have appointed him [David, representing the Messiah] to be a witness to the nations [regarding salvation],
A leader and commander to the peoples.
