'Elder' in the Bible

Do not accept an accusation against an elder except on the evidence of two or three witnesses.

Therefore [I, your] fellow elder and a witness of the sufferings of Christ, [and] also a sharer of the glory that is going to be revealed, exhort the elders among you:

The elder, to the elect lady and her children, whom I love in truth--and not I alone, but also all those who know the truth--

The elder, to Gaius the beloved, whom I love in [the] truth.
