'Younger' in the Bible

Do not address an older man harshly but appeal to him as a father. Speak to younger men as brothers,

older women as mothers, and younger women as sisters -- with complete purity.

But do not accept younger widows on the list, because their passions may lead them away from Christ and they will desire to marry,

So I want younger women to marry, raise children, and manage a household, in order to give the adversary no opportunity to vilify us.
