1. 16:21 He: the Marcan parallel (Mk 8:31) has “the Son of Man.” Since Matthew has already designated Jesus by that title (Mt 15:13), its omission here is not significant. The Matthean prediction is equally about the sufferings of the Son of Man. Must: this necessity is part of the tradition of all the synoptics; cf. Mk 8:31; Lk 9:21. The elders, the chief priests, and the scribes: see note on Mk 8:31. On the third day: so also Lk 9:22, against the Marcan “after three days” (Mk 8:31). Matthew’s formulation is, in the Greek, almost identical with the pre-Pauline fragment of the kerygma in 1 Cor 15:4 and also with Hos 6:2, which many take to be the Old Testament background to the confession that Jesus was raised on the third day. Josephus uses “after three days” and “on the third day” interchangeably (Antiquities 7:280–81; 8:214, 218) and there is probably no difference in meaning between the two phrases.
2. 16:22–23 Peter’s refusal to accept Jesus’ predicted suffering and death is seen as a satanic attempt to deflect Jesus from his God-appointed course, and the disciple is addressed in terms that recall Jesus’ dismissal of the devil in the temptation account (Mt 4:10: “Get away, Satan!”). Peter’s satanic purpose is emphasized by Matthew’s addition to the Marcan source of the words You are an obstacle to me.
3. 16:24–28 A readiness to follow Jesus even to giving up one’s life for him is the condition for true discipleship; this will be repaid by him at the final judgment.
4. 16:24 Deny himself: to deny someone is to disown him (see Mt 10:33; 26:34–35) and to deny oneself is to disown oneself as the center of one’s existence.
