'Youngest' in the Bible

So Othniel son of Kenaz, Caleb’s youngest brother, captured it, and Caleb gave his daughter Achsah to him as his wife.

The Israelites cried out to the Lord. So the Lord raised up Othniel son of Kenaz, Caleb’s youngest brother, as a deliverer to save the Israelites.

He said to Him, “Please, Lord, how can I deliver Israel? Look, my family is the weakest in Manasseh, and I am the youngest in my father’s house.”

He went to his father’s house in Ophrah and killed his 70 brothers, the sons of Jerubbaal, on top of a large stone. But Jotham, the youngest son of Jerubbaal, survived, because he hid himself.
