Mark 3:6 - Matthew Poole's English Annotations on the Holy Bible

Ver. 6-12. Who these Herodians were we cannot learn plainly from holy writ; it is most probable that they were a civil faction, who took Herod's part, and were stiff for promoting 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 Judea anciently, as may be gathered from Joshua 15:1, and Numbers 34:3, 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.
