Many writers take the phrase, “Light of Israel” as a name of God. It occurs in a passage in which God warns arrogant Assyria that He is about to destroy her.
Some rabbis thought that “Light” was a title for the coming Messiah (Christ).
Light of Israel in Hebrew:
Strong’s Concordance numbers: 216, 3478
Bible reference: Isa. 10:17
And the light of Israel shall be for a fire, and his Holy One for a flame: and it shall burn and devour his thorns and his briers in one day. (Isaiah 10:17 KJV)
A similar name of God is My light, He is also My lamp. Jesus (Yeshua‘) declared “I am the light of the world.”
