² tn The Piel participle used here is from the same root as the name “Isaac.” In the Piel stem the verb means “to jest; to make sport of; to play with,” not simply “to laugh,” which is the meaning of the verb in the Qal stem. What exactly Ishmael was doing is not clear. Interpreters have generally concluded that the boy was either (1) mocking Isaac (cf. NASB, NIV, NLT) or (2) merely playing with Isaac as if on equal footing (cf. NAB, NRSV). In either case Sarah saw it as a threat. The same participial form was used in Gen 19:14 to describe how some in Lot’s family viewed his attempt to warn them of impending doom. It also appears later in Gen 39:14, 17, where Potiphar accuses Joseph of mocking them.

¹ sn In what sense does Jesus refer to his own ‘sanctification’ with the phrase I set myself apart? In 10:36 Jesus referred to himself as “the one whom the Father sanctified and sent into the world,” which seems to look at something already accomplished. Here, however, it is something he does on behalf of the disciples (on their behalf) and this suggests a reference to his impending death on the cross. There is in fact a Johannine wordplay here based on slightly different meanings for the Greek verb translated set apart (ἁγιάζω, hagiazō). In the sense it was used in 10:36 of Jesus and in 17:17 and here to refer to the disciples, it means to set apart in the sense that prophets (cf. Jer 1:5) and priests (Exod 40:13, Lev 8:30, and 2 Chr 5:11) were consecrated (or set apart) to perform their tasks. But when Jesus speaks of setting himself apart (consecrating or dedicating himself) on behalf of the disciples here in 17:19 the meaning is closer to the consecration of a sacrificial animal (Deut 15:19). Jesus is “setting himself apart,” i.e., dedicating himself, to do the will of the Father, that is, to go to the cross on the disciples’ behalf (and of course on behalf of their successors as well).

¹ sn There are various interpretations of v. 15. For example, the author could be saying simply, “I will make every effort that you remember these things.” But the collocation of σπουδάζω (spoudazō) with μνήνη (mnēnē) suggests a more specific image. R. Bauckham (Jude, 2 Peter [WBC], 201-2) is right when he notes that these two words together suggest a desire to write some sort of letter or testament. Most commentators recognize the difficulty in seeing the future verb σπουδάσω (spoudasō) as referring to 2 Peter itself (the present or aorist would have been expected, i.e., “I have made every effort,” or “I am making every effort”). Some have suggested that Mark’s Gospel is in view. The difficulty with this is threefold: (1) Mark is probably to be dated before 2 Peter, (2) early patristic testimony seems to imply that Peter was the unwitting source behind Mark’s Gospel; and (3) “these things” would seem to refer, in the least, to the prophecy about Peter’s death (absent in Mark). A more plausible suggestion might be that the author was thinking of the ending of John’s Gospel. This is possible because (1) John 21:18-19 is the only other place in the NT that refers to Peter’s death; indeed, it fleshes out the cryptic statement in v. 14 a bit more; (2) both 2 Peter and John were apparently written to Gentiles in and around Asia Minor; (3) both books were probably written after Paul’s death and perhaps even to Paul’s churches (cf. 2 Pet 3:1-2, 15-16); and (4) John 21 gives the appearance of being added to the end of a finished work. There is thus some possibility that this final chapter was added at the author’s request, in part to encourage Gentile Christians to face impending persecution, knowing that the martyrdom of even (Paul and) Peter was within the purview of God’s sovereignty. That 2 Pet 1:15 alludes to John 21 is of course by no means certain, but remains at least the most plausible of the suggestions put forth thus far.

¹ sn Do we take this commission at face value? Does the Lord really want to prevent his people from understanding, repenting, and being healed? Verse 9, which ostensibly records the content of Isaiah’s message, is clearly ironic. As far as we know, Isaiah did not literally proclaim these exact words. The Hebrew imperatival forms are employed rhetorically and anticipate the response Isaiah will receive. When all is said and done, Isaiah might as well preface and conclude every message with these ironic words, which, though imperatival in form, might be paraphrased as follows: “You continually hear, but don’t understand; you continually see, but don’t perceive.” Isaiah might as well command them to be spiritually insensitive because, as the preceding and following chapters make clear, the people are bent on that anyway. (This ironic command is comparable to saying to a particularly recalcitrant individual, “Go ahead, be stubborn!”) Verse 10b is also clearly sarcastic. On the surface it seems to indicate Isaiah’s hardening ministry will prevent genuine repentance. But, as the surrounding chapters clearly reveal, the people were hardly ready or willing to repent. Therefore, Isaiah’s preaching was not needed to prevent repentance! Verse 10b reflects the people’s attitude and might be paraphrased accordingly: “Otherwise they might see with their eyes, hear with their ears, understand with their mind, repent, and be restored, and they certainly wouldn’t want that, would they?” Of course, this sarcastic statement may also reveal that the Lord himself is now bent on judgment, not reconciliation. Just as Pharaoh’s rejection of Yahweh’s ultimatum ignited judgment and foreclosed, at least temporarily, any opportunity for repentance, so the Lord may have come to the point where he has decreed to bring judgment before opening the door for repentance once more. The sarcastic statement in verse 10b would be an emphatic way of making this clear. (Perhaps we could expand our paraphrase: “Otherwise they might…repent, and be restored, and they certainly wouldn’t want that, would they? Besides, it’s too late for that!”) Within this sarcastic framework, verse 10a must also be seen as ironic. As in verse 9 the imperatival forms should be taken as rhetorical and as anticipating the people’s response. One might paraphrase: “Your preaching will desensitize the minds of these people, make their hearing dull, and blind their eyes.” From the outset the Lord might as well command Isaiah to harden the people because his preaching will end up having that effect. Despite the use of irony, we should still view this as a genuine, albeit indirect, act of divine hardening. After all, God did not have to send Isaiah. By sending him, he drives the sinful people further from him, for Isaiah’s preaching, which focuses on the Lord’s covenantal demands and impending judgment upon covenantal rebellion, forces the people to confront their sin and then continues to desensitize them as they respond negatively to the message. As in the case of Pharaoh, Yahweh’s hardening is not arbitrarily imposed on a righteous or even morally neutral object. Rather his hardening is an element of his righteous judgment on recalcitrant sinners. Ironically, Israel’s rejection of prophetic preaching in turn expedites disciplinary punishment, and brings the battered people to a point where they might be ready for reconciliation. The prophesied judgment (cf. 6:11-13) was fulfilled by 701 b.c. when the Assyrians devastated the land (a situation presupposed by Isa 1:2-20; see especially vv. 4-9). At that time the divine hardening had run its course and Isaiah is able to issue an ultimatum (1:19-20), one which Hezekiah apparently took to heart, resulting in the sparing of Jerusalem (see Isa 36-39 and cf. Jer 26:18-19 with Mic 3:12).This interpretation, which holds in balance both Israel’s moral responsibility and the Lord’s sovereign work among his people, is consistent with other pertinent texts both within and outside the Book of Isaiah. Isa 3:9 declares that the people of Judah “have brought disaster upon themselves,” but Isa 29:9-10 indicates that the Lord was involved to some degree in desensitizing the people. Zech 7:11-12 looks back to the pre-exilic era (cf. v. 7) and observes that the earlier generations stubbornly hardened their hearts, but Ps 81:11-12, recalling this same period, states that the Lord “gave them over to their stubborn hearts.”
