Isaiah 28:5
בַּיּוֹם הַהוּא יִהְיֶה ה' צְבָקוֹת לַעֲטֶרֶת צְבִי וְלִצְפִירַת תִּפְאָרָה לִשְׁאָר עַמּוֹ
On that day, the L-rd of hosts will be a crown of beauty and a diadem of glory for the rest of His people.
"That day," the Radak tells us, refers to the day when the ten Tribes would be exiled by the Assyrian invaders, "the rest of His people" referring to the Tribes of Judah and Benjamin, which were not exiled at that time. The king of the two remaining Tribes at the time of the Assyrian exile was Chizkiyahu (Hezekiah). He did what was right in G-d's eyes making a "crown of beauty," in contrast with the arrogance of the ten Tribes.
