Isaiah 16:5

And in mercy shall the throne be established: and he shall sit upon it in truth in the tabernacle of David, judging, and seeking judgment, and hasting righteousness.

And in mercy shall the throne be established. If Judah shelters the suppliant Moab, allowing him to remain in Idumea, a blessing will redound to Judah itself and its "throne."

And he shall sit upon it in truth in the tabernacle of David, judging, and seeking judgment, and hasting righteousness - language so divinely framed as to apply to 'the latter days' under King Messiah, when "the Lord shall bring again the captivity of Moab," as the result of the restoration of Israel and Judah (; ; ; ; ).

Hasting - prompt in executing.
