'Course' in the Bible

And the tongue is a fire, a world of iniquity: so is the tongue among our members, that it defileth the whole body, and setteth on fire the course of nature; and it is set on fire of hell.

let the [latter] one know that the one who has turned a sinner from the error of his way will save that one’s soul from death and cover a multitude of sins [that is, obtain the pardon of the many sins committed by the one who has been restored].
