'Fellow servant' in the Bible

"His fellow servant therefore fell at his feet and entreated him, "'Only give me time,' he said, 'and I will pay you.'

ought not you also to have had pity on your fellow servant, just as I had pity on you?'

as you learned it from Epaphras our dearly-loved fellow servant. He is to you a faithful minister of Christ in our stead,

Tychicus, our much-loved brother, a trusty assistant and fellow servant with us in the Lord's work, will give you every information about me.
