Albert Barnes Commentary Matthew 2:19

"But when Herod was dead, behold, an angel of the Lord appeareth in a dream to Joseph in Egypt, saying," — Matthew 2:19 (ASV)

Herod was dead. See Barnes on Matthew 2:15.

Herod left three sons, and the kingdom was at his death divided between them. To Archelaus was given Judea, Idumea, and Samaria; to Philip, Batanea, Trachonitis, etc.; to Antipas, Galilee and Perea. Each of these was also called Herod, and these are the individuals who are so frequently referred to in the New Testament during the ministry of the Saviour and the labours of the apostles. The following table will show at a glance the chief connections of this family, as far as they are mentioned in the sacred history.
