To see (θεάσασθαι)
Rev., to behold. θεᾶσθαι, like θεωρεῖν, expresses the calm, continuous contemplation of an object which remains before the spectator. Compare Joh 1:14. Another verb is used in Christ's repetition of the question, Mat 11:8, Mat 11:9; ἰδεῖν in the ordinary sense of seeing. The more earnest expression suits the first question.
