When Herod the king had heard these things, he was {c} troubled, and all Jerusalem with him.

(c) Was much moved, for he was a foreigner, and became ruler by force; and the Jews were troubled; for wickedness is mad and raging.

People's New Testament

2:3 Herod... was troubled. The trouble of Herod is easily accounted for. He was a usurper. This news seemed to portend a legitimate king, a rival for the throne, around whom the Jewish nation would rally.

All Jerusalem with him. The capital was in commotion. It was the seat of Herod's power, and his staunchest supporters were there.

Jamieson-Fausset-Brown Bible Commentary

3. When Herod the king had heard these things, he was troubled-viewing this as a danger to his own throne: perhaps his guilty conscience also suggested other grounds of fear.

and all Jerusalem with him-from a dread of revolutionary commotions, and perhaps also of Herod's rage.

Matthew Henry's Concise Commentary

2:1-8 Those who live at the greatest distance from the means of grace often use most diligence, and learn to know the most of Christ and his salvation. But no curious arts, or mere human learning, can direct men unto him. We must learn of Christ by attending to the word of God, as a light that shineth in a dark place, and by seeking the teaching of the Holy Spirit. And those in whose hearts the day-star is risen, to give them any thing of the knowledge of Christ, make it their business to worship him. Though Herod was very old, and never had shown affection for his family, and was not himself likely to live till a new-born infant had grown up to manhood, he began to be troubled with the dread of a rival. He understood not the spiritual nature of the Messiah's kingdom. Let us beware of a dead faith. A man may be persuaded of many truths, and yet may hate them, because they interfere with his ambition, or sinful indulgences. Such a belief will make him uneasy, and the more resolved to oppose the truth and the cause of God; and he may be foolish enough to hope for success therein.
