וְהָיָ֤ה אֽוֹר־יִשְׂרָאֵל֙ לְאֵ֔שׁ וּקְדוֹשׁ֖וֹ לְלֶהָבָ֑ה וּבָעֲרָ֗ה וְאָֽכְלָ֛ה שִׁית֥וֹ וּשְׁמִיר֖וֹ בְּי֥וֹם אֶחָֽד׃
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.
Read halakhic rulings (Jewish law) on Isaiah 10:17: and classical halakhic sources.
