'Youngest' in the Bible

He said to him, "Excuse me, my lord. How will I deliver Israel? Look, my clan [is] the weakest in Manasseh, and I [am] the youngest in my father's house."

And he went to his father's house at Ophrah, and he killed his brothers, the sons of Jerub-Baal, seventy men, on one stone. But Jotham the youngest son of Jerub-Baal survived, because he hid himself.
