Kedosh Yisrael — The Holy One of Israel
קְדוֹשׁ יִשְׂרָאֵל
The Holy One of Israel — Isaiah's signature title, born in his throne-room vision.
Holiness bound BY NAME to a people — the transcendent One who attaches Himself to Israel. Jewish liturgy's Kedushah circles it daily; the NT's 'Holy One of God' carries Isaiah's title onto Galilean soil.
