'One' in the Bible

If anyone is blameless, [the] husband of one wife, having faithful children, not {accused of dissipation} or rebellious.

A certain one of them, [one of] their own prophets, has said, "Cretans [are] always liars, evil beasts, lazy gluttons."

Speak these [things] and exhort and reprove with all authority. Let no one disregard you.

to speak evil of no one, to be peaceable, gentle, showing all courtesy to all people.

For we also were once foolish, disobedient, led astray, enslaved to various desires and pleasures, spending our lives in wickedness and envy, despicable, hating one another.
