“Devil.” The Greek word is diabolos (#1228 διάβολος), which literally means “Slanderer,” but diabolos gets transliterated into English as our more familiar name, “the Devil.” Slander is so central to who the Devil is and how he operates that one of his primary names is “the Slanderer.” [For more information on the names of the Devil, see Appendix 14: “Names of the Devil”].
“Look!” The Greek word is idou (#2400 ἰδού), and it is used to get our attention. See commentary on Matthew 1:20 (“Look!).
“were ministering.” See commentary on Mark 1:13.
