Dog or whole-hearted
Kalub is a modern phonetic spelling variant of the Hebrew name Caleb. In the Old Testament, Caleb was one of the twelve spies sent by Moses into Canaan, known for his faith and courage. The name is often interpreted as 'dog' (symbolizing loyalty) or derived from the Hebrew words 'kol' and 'lev' meaning 'whole heart'.
