Isaiah 47:12

Stand now with thy enchantments - (See the notes at Isaiah 47:9). This is evidently sarcastic and ironical. It is a call on those who practiced the arts of magic to stand forth, and to show whether they were able to defend the city, and to save the nation.

Wherein thou hast labored - Or in practicing which thou hast been diligently employed.

From thy youth - From the very commencement of thy national existence. Babylon was always distinguished for these arts. Now was a time when their value was to be put to the test, and when it was to be seen whether they were able to save the nation.

If so be - Or perhaps or possibly, they may be able to profit thee - the language of irony. Perhaps by the aid of these arts you may be able to repel your foes.
