Ucal is a name appearing with Ithiel in Proverbs 30:1, though the passage is highly obscure. It may be a personal name, a symbolic designation, or part of a phrase describing Agur’s weariness.
Ucal occurs only in the superscription or opening words of Agur’s sayings in Proverbs. The received text treats it as a proper name, while some ancient versions and interpreters understand the wording differently.
Some interpreters have suggested that Ucal may correspond to the Caleol mentioned in 1 Kings 4:31. Others read the word as a verb meaning “I am consumed.”
