Ucal
(I am strong). According to the received text of (Proverbs 30:1) Ithiel and Ucal must be regarded as proper names; and if so, they must be the names of disciples or sons of Agur the son of Jakeh, an unknown sage among the Hebrews. But there is great obscurity about the passage. Ewald considers both Ithiel and Ucal as symbolical names, employed by the poet to designate two classes of thinkers to whom he addresses himself.
