'Older' in the Bible

Now the older son was in the field: and when he came near the house, the sounds of music and dancing came to his ears.

And they sent a letter by them, saying, The Apostles and the older brothers, to the brothers who are of the Gentiles in Antioch and Syria and Cilicia, may joy be with you:

It was said to her, The older will be the servant of the younger.

To the older women as to mothers, to the younger as to sisters, with a clean heart.

And in the same way, let the younger men be ruled by the older ones. Let all of you put away pride and make yourselves ready to be servants: for God is a hater of pride, but he gives grace to those who make themselves low.
