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,” etc.; but, “They that at new moons make known from (by means of) them the things that shall come upon thee” [Maurer].
