Matthew Poole and continuators on Mark 3:12

12 And he straitly charged them, that they should not make him known.

Who these Herodians were, we cannot learn plainly from holy Writ, it is most probable, that they were a Civil Faction, who took Herods part, and were stiff for promoving his interest, and the interest of the Roman Emperor (whose substitute Herod was) with these the Pharisees (in other Cases their implacable Enemies) mix Counsels how they might destroy Christ. Christ gives place to their fury, his time being not yet come, and withdraweth himself from their sight, being followed by great multitudes, who in the fame of his Miracles, or the hopes they had of receiving some good from him for themselves, or for their Friends drew after him. Some of these are said to have come from Idumea, which was the Country of Edom, and distinct from Iudea Anciently, as may be gathered form Ios. 15.1. and Numb. 34. but whether it was at this time so or no, is doubted. Our Lord Commandeth the Devils not to make him known, not desiring any such Preachers.
