“Search the Scriptures” is the traditional rendering of the opening words of John 5:39. The supplied interpretation understands the sentence not as a command but as a declaration: Jesus’ hearers were searching the Scriptures because they thought that in them they had eternal life.
The statement occurs in Jesus’ discourse concerning the Scriptures and their witness. On the indicative reading, it exposes the hearers’ activity and expectation while showing that they failed to come to Jesus, to whom the Scriptures testify.
The interpretation depends on taking the Greek verb as indicative rather than imperative. The supplied material notes that the Greek permits this reading and cites earlier and later scholars who defended it.
