Isaiah 47:12
Stand now with thine enchantments, and with the multitude of thy sorceries, wherein thou hast laboured from thy youth; if so be thou shalt be able to profit, if so be thou mayest prevail.
Stand now with thine enchantments, and with the multitude of thy sorceries,.... An ironic expression, deriding those evil arts, bidding defiance to them, calling upon the masters of them to do their utmost by them:
wherein thou hast laboured from thy youth; from the infancy of their state; as soon as their monarchy was founded, or they became a people, they were given to these practices, and were famous for them; and in which, no doubt, many among them were brought up from their youth; and to gain the knowledge of which they were at great labour and expense; and yet it was all in vain, and to no purpose:
if so be thou shall be able to profit, if so be thou mayest prevail; if skill in these things can be of any advantage to keep off the impending calamity, and fortify against the powerful enemy that will quickly surprise thee; try if by thine art thou canst foresee the danger, and prevent it.
