Mark 8:10-21
Beware of unbelief
I. The demand for signs.
That the Pharisees “came forth” indicates that they made a deliberate effort to go where He was. Perhaps He was avoiding confrontation as much as possible and was not in a heavily populated area. At any rate, the Pharisees—as protectors of official Judaism—tried an entirely new strategy, expressed (v. 11) as questioning Him, seeking a sign by Him, and tempting Him. All three were, no doubt, one and the same: the question they pressed on Him was for a sign, and in doing that they were testing Him
Sign” (Greek semeion) is originally a distinguishing mark, thus a mark or act that indicates or signifies something: in this case “an outward compelling proof of divine authority—something which unbelief demands but Jesus resolutely refuses to give” (Cranfield 257). Here, as often (but not always: see Mt. 26:48), it effectively comes to mean a supernatural work. We may not be able to surmise exactly what kind of “sign” the Pharisees had in mind, but they wanted something that would clearly attest that Jesus was from God: perhaps “some startling celestial phenomenon” (Hiebert 222). Given the great number of miraculous works He had performed, they should not have needed anything else; apparently, therefore, they wanted something more spectacular. “Sign-seeking strikes at the root of the biblical concept of the nature of faith … (Jn. 4:48)” (Cole 129). “It precludes personal decision in response to the word of revelation” (Lane 278).
“Tempting” (Greek peirazo) can be used either for putting someone or something to a test, or for an enticement to wrongdoing. In one sense, neither of these can exist without the other since any testing involves temptation and vice versa. But at various times one or the other of these meanings is more prominent, and here the idea of testing or proving is the more prominent. They wanted Jesus to prove Himself to them. The implication is that they did not believe He could do what they asked and that by His failure He would expose Himself.
