OUR FATHER WHOSE GREAT SALVATION IS THE SON OF DAVID WHO IS ENTHRONED IN ZION
Isaiah chapter 16 verse 3 ( Amplified ) says this;
[Say to the ruler] “Give us advice, make a decision [for Moab, king of Judah]; Cast your shadow [over us] like night in the midst of noon; Hide the outcasts, do not betray the fugitive [to his pursuer].
This passage captures a desperate plea from the Moabites to the King of Judah.
Moab was undergoing a period of severe judgement that had caused their society to break apart and the Moabites were fleeing as refugees into foreign territories to escape the terror in their own country.
Women fleeing north from Moab had come to the Arnon river and were trying to cross it but were like fluttering or wandering birds unable to go forward or return.
The Moabites needed to be allowed to cross into Judah's lands where they could be hidden so that they could escape the destroyer. They requested that they be given refuge in Judah until the oppression ended and the destruction ceased and the aggressor vanished from the land.
In the midst of the record of Moab's panicked call to the king of Judah for salvation, Isaiah prophesied the Mesianic throne in verse 5;
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.
Even as Moab, in their time of distress, appealed to the throne in Jerusalem, Isaiah projects forward into the future and prophesied of when the whole world will appeal to the throne in Zion upon which the Son of David will sit.
Whereas Moab could only be partially helped by the king of Judah, the Lord Jesus, the Son of David, on the throne of Zion is the great salvation of all who call upon His name.
