50. πάντες γὰρ εἶδαν. See on Mar 6:29. It was no subjective delusion; there was something objective which all of them perceived. The aorists indicate what was of short duration; He addressed them at once, and their trouble was at an end. Syr-Sin. has “when they all saw Him, they cried out.” The difference between λαλέω, “speak,” and λέγω, “say,” is manifest here. Trench, Syn. § 76.
Θαρσεῖτε. Cf. Mar 10:49; Mat 9:2; Mat 9:22; Joh 16:33. This form prevails in Gospels and Acts, θαρρέω in 2 Cor. and Heb. In LXX. θαρσέω is common, θαρρέω rare and late.
μὴ φοβεῖσθε. Cease to fear: Mar 5:36, Mar 10:14. Contrast the aorists in Mar 10:19. For the asyndeton see on Mar 6:38.
