isaiah 47:13 Thou art wearied in the multitude of thy counsels. Let now the astrologers, the stargazers, the monthly prognosticators, stand up, and save thee from these things that shall come upon thee. - Free Bible Online

      13. wearied--(compare Isa 57:10; Eze 24:12).
      astrologers--literally, those who form combinations of the heavens; who watch conjunctions and oppositions of the stars. "Casters of the configurations of the sky" [HORSLEY]. GESENIUS explains it: the dividers of the heavens. In casting a nativity they observed four signs:--the horoscope, or sign which arose at the time one was born; the mid-heaven; the sign opposite the horoscope towards the west; and the hypogee.
      monthly prognosticators--those who at each new moon profess to tell thereby what is about to happen. Join, not as English Version, "save . . . from those things," &c.; but, "They that at new moons make known from (by means of) them the things that shall come upon thee" [MAURER].
