Albert Barnes Commentary Daniel 3:10-11

"Thou, O king, hast made a decree, that every man that shall hear the sound of the cornet, flute, harp, sackbut, psaltery, and dulcimer, and all kinds of music, shall fall down and worship the golden image; and whoso falleth not down and worshippeth, shall be cast into the midst of a burning fiery furnace." — Daniel 3:10-11 (ASV)

Thou, O king, hast made a decree ... — See Daniel 3:4-5. As the decree included every man who heard the sound of the music, it of course embraced the Jews, whatever religious scruples they might have. Whether their scruples, however, were known at the time is not certain; or whether they would have been regarded if known, is no more certain.
