כִּֽי־בָעֲרָ֤ה כָאֵשׁ֙ רִשְׁעָ֔ה שָׁמִ֥יר וָשַׁ֖יִת תֹּאכֵ֑ל וַתִּצַּת֙ בְּסִֽבְכֵ֣י הַיַּ֔עַר וַיִּֽתְאַבְּכ֖וּ גֵּא֥וּת עָשָֽׁן׃
For wickedness burneth as the fire; it devoureth the briers and thorns; yea, it kindleth in the thickets of the forest, And they roll upward in thick clouds of smoke.
Read halakhic rulings (Jewish law) on Isaiah 9:17: and classical halakhic sources.
