Romans 5:20

Entered. — A graphic metaphorical expression: “Came in to the side of” the sin already existing; “took its place,” as it were, “by the side of” sin, and joined forces with it, thus greatly adding to its extent and power.

Abound. — This word should be reserved for the last of the three places in this verse in which it appears in the Authorised version. The original in the other two places is different, and has the force of “Might be multiplied,” or “increased” — i.e., made more and made worse.
