Romans 13:7
Pay promptly to all men what is due to them: taxes to those to whom taxes are due, toll to those to whom toll is due, respect to those to whom respect is due, honour to those to whom honour is due.
1 Timothy 5:1
Never administer a sharp reprimand to a man older than yourself; but entreat him as if he were your father, and the younger men as brothers;
Titus 2:6
In the same way exhort the younger men to be discreet,
1 Peter 5:5
In the same way you younger men must submit to your elders; and all of you must gird yourselves with humility towards one another, for God sets Himself against the proud, but gives grace to the humble.
