Caleb was the son of Jephunneh and a leader of Israel after Joshua had died. Caleb was one of the 12 spies sent out to look at the land.
He was bold, impetuous, courageous, consecrated to God, vigorous and faithful in old age and invincible because he drove out the giants from his inheritance.
Caleb was given the land promised to him by Joshua, which was the land of the Anakims, Kirjatharba or Hebron and the neighboring hill country.
Caleb in Hebrew means: a dog.
He was a prince of Judah as the leader of the Hezronites, while Nahshon was the prince of the whole tribe of Judah.
26 The LORD said to Moses and Aaron:27 "How long will this wicked community grumble against me? I have heard the complaints of these grumbling Israelites. 28 So tell them, ‘As surely as I live, declares the LORD, I will do to you the very things I heard you say: 29 In this desert your bodies will fall—every one of you twenty years old or more who was counted in the census and who has grumbled against me. 30 Not one of you will enter the land I swore with uplifted hand to make your home, except Caleb son of Jephunneh and Joshua son of Nun.
Caleb was 40 years old when he went in as one of the 12 spies.
