'Younger' in the Bible

The younger of them said to his father, "'Father, give me the share of the property that comes to me.' "So he divided his wealth between them.

No long time afterwards the younger son got all together and travelled to a distant country, where he wasted his money in debauchery and excess.

With you it is not so; but let the greatest among you be as the younger, and the leader be like him who serves.
