Metaphysical meaning of Jehoiada (mbd)
Jehoiada, je-hoi'-a-då (Heb.)--whom Jehovah knows; whom Jah perceives; who knows Jehovah; who apprehends Jah, i. e., lays hold of; knowledge of Jah; understanding of Jehovah.
a A priest who was instrumental in establishing Jehoash, or Joash, on the throne of Judah, and in putting away much of the idolatry of the people (II Kings 11:4 to 12:9). b There are other Israelites by this name also (II Sam. 8:18; Jer. 29:26).
Jehoash, or Joash, king of Jerusalem was a good king and did that which was right in the sight of God, so long as Jehoiada lived to guide him; after Jehoiada's death he did evil. This shows the necessity of the will's being guided by the inner Spirit of wisdom and justice.
