Isaiah 47:15

15.So shal they be to thee. After having threatened destruction to those astronomers, he again retums to the Babylonians, and threatens that they must not look for assistance from that quarter from which they expected it, and that they ought not to rely on those vain counsels, with which they had long and eagerly vexed themselves in vain.

He calls them dealers, or, as we commonly say, traffickers; a metaphor taken from merchants, who are skilled in innumerable arts of deceiving, and in impostures of every kind; for the princes do not consult in a manner suitable to their rank, but traffic in disgraceful transactions. (232) Though we may extend this to all the allies by whom the Babylonians were aided, yet the Prophet has his eye chiefly on the diviners. When he adds, from thy youth, he aggravates the guilt of Babylon, in having been infected with this foolish belief from an ancient date, and in having held this error as if it had been born with her.

Every one to his own quarter. (233) It is supposed that the Prophet here speaks of the flight of the astrologers, that every one shall provide for his own safety; and I fully agree with this, but think that, there is also an allusion to the “quarters” of the heavens, which astrologers divide and measure, so as to deduce their prognostications from them. He therefore ridicules their vain boasting. “Theyshall withdraw into their quarters, but they shall go astray, and there shall be no means of protection. If any one choose to apply it to the revolt of those whose assistance Babylon thought that at any time she could easily obtain, I have no objection.
