The name Caleb can come from the combination of the Hebrew words kal (whole) and lev (heart), creating the meaning "whole-hearted". a symbol of loyalty.
Biblical significance: Caleb is a figure in the Old Testament who, along with Joshua, was sent by Moses to spy on the land of Canaan. Unlike the other spies, he had faith that God's promises would be fulfilled and was one of only two Israelites from the Exodus generation to enter the Promised Land.
