AI Summary
Fellow worker — someone who works together with another, a helper or partner in work or labor 1234. It is used of people who labor alongside someone else in a task, sometimes described as a fellow worker "of" a person, "of God," "in the truth," or "for" some cause 1. In wider Greek usage the word can also describe joining in or helping toward a piece of work generally, but the biblical use is specifically of a companion in labor 32.
