Isaiah 28:5

“In that day shall the Lord of hosts be for a crown of glory, &c.] Or, “glorious crown”f550; surrounding, adorning, and protecting his people; granting them his presence; giving them his grace, and large measures of it; causing them to live soberly, righteously, and godly: this stands opposed to “the crown of pride” before mentioned, and refers to the time when that should be trampled under foot, or when the ten tribes should be carried into captivity, which was in the sixth year of Hezekiah’s reign, (<121810>2 Kings 18:10) at which time, and in whose reign, as well as in the reign of Josiah, this prophecy had its accomplishment: and for a diadem of beauty: or, “a beautiful diadem”f551; the…”

“The prophet now turns to Judah; a gracious promise to the remnant ("residue"); a warning lest through like sins Judah should share the fate of Samaria. crown--in antithesis to the "fading crown" of Ephraim (Isa 28:1, Isa 28:3). the residue--primarily, Judah, in the prosperous reign of Hezekiah (Kg2 18:7), antitypically, the elect of God; as He here is called their "crown and diadem," so are they called His (Isa 62:3); a beautiful reciprocity.”

“28:5-6 In the future, after God’s judgment has purged his people, he will restore a righteous remnant, transforming the desires and character of his people. Samaria will no longer be the source of Israel’s pride; instead, they will glory in the Lord, their true crown.”

“The threat is now followed by a promise. This is essentially the same in character as Isa 4:2-6. The place of the false glory thus overthrown is now filled by a glory that is divine and true. "In that day will Jehovah of hosts be the adorning crown and the splendid diadem to the remnant of His people; and the spirit of justice to them that sit on the judgment-seat, and heroic strength to them that drive back war at the gate." "The remnant of His people" (שׁאר with a fixed kametz, as in Isa 21:17) is not Judah, as distinguished from Ephraim that had utterly perished; but Judah and the remaining portion of Ephraim, as distinguished from the portion which had perished.
