Nabal—as of the house of Caleb— כלבי kalibi, in the Hebrew, and he was a Calebite. As כלב caleb signifies a dog, some of the ancient interpreters understand the word as expressive of his bad disposition; whence the Syriac, Arabic, and LXX translate it, a man of a churlish, snarling, or dog-like disposition, ανθρωπος Κυνικος. See Le Clerc and Calmet.
