UCAL
One of the two characters, sons, disciples or contemporaries, to whom Agur addresses the words of chapter 30 of Proverbs (Proverbs 30:1, 4).
This interpretation corresponds to the Heb. punctuation. traditional and is based on v. 4, in which some questions are asked. Another interpretation is seen in Heb. “oukal” a verb, and in this case it translates: “I am consumed, I am on a limb.”
