TRANSGRES'SION. Heb 2:2. The two words "transgression" and "disobedience" used in this passage are by common usage nearly synonymous. The former may be considered as passing over the bounds prescribed by a law, or doing the things we ought not to do, and "disobedience" as a refusal to do what it enjoins, or not doing; the things we ought to do. The two words are here united, so that every violation of the command may be included.
