¹ tn The noun רָקָב (raqav, “rottenness, decay”) refers to wood rot caused by the ravages of worms (BDB 955 s.v. רָקָב); cf. NLT “dry rot.” The related noun רִקָּבוֹן (riqqavon) refers to “rotten wood” (Job 41:27).

³ sn For the metaphor of the Lord going forth against his enemies like an attacking lion, see Jer 49:19; 50:44; and Isa 31:4, in all of which the Lord comes against the nations in defense of his people. In Hos 5:14 the metaphor is turned against his own people. The figure of a lion ravaging people has already been used in Jer 4:7 of the enemy from the north (Babylon).

¹ tn Or “began to harm [the church] severely.” If the nuance of this verb is “destroy,” then the imperfect verb ἐλυμαίνετο (elumaineto) is best translated as a conative imperfect as in the translation above. If instead the verb is taken to mean “injure severely” (as L&N 20.24), it should be translated in context as an ingressive imperfect (“began to harm the church severely”). Either option does not significantly alter the overall meaning, since it is clear from the stated actions of Saul in the second half of the verse that he intended to destroy or ravage the church.

³ sn How direct this hardening is, one cannot be sure. The speaker may envision direct involvement on the Lord’s part. The Lord has brought the exile as judgment for the nation’s sin and now he continues to keep them at arm’s length by blinding them spiritually. The second half of 64:7 might support this, though the precise reading of the final verb is uncertain. On the other hand, the idiom of lament is sometimes ironic and hyperbolically deterministic. For example, Naomi lamented that Shaddai was directly opposing her and bringing her calamity (Ruth 1:20-21), while the author of Ps 88 directly attributes his horrible suffering and loneliness to God (see especially vv. 6-8, 16-18). Both individuals make little, if any, room for intermediate causes or the principle of sin and death which ravages the human race. In the same way, the speaker in Isa 63:17 (who evidences great spiritual sensitivity and is anything but “hardened”) may be referring to the hardships of exile, which discouraged and even embittered the people, causing many of them to retreat from their Yahwistic faith. In this case, the “hardening” in view is more indirect and can be lifted by the Lord’s intervention. Whether the hardening here is indirect or direct, it is important to recognize that the speaker sees it as one of the effects of rebellion against the Lord (note especially 64:5-6).
