Yesaya 53:4

53:4 But he lifted up our illnesses,

he carried our pain; ¹ 

even though we thought he was being punished,

attacked by God, and afflicted for something he had done. ² 

Zakharia 13:7

13:7 “Awake, sword, against my shepherd,

against the man who is my associate,”

says the Lord who rules over all.

Strike the shepherd that the flock may be scattered; ³ 

I will turn my hand against the insignificant ones.

[53:4]  ¹ sn Illness and pain stand by metonymy (or perhaps as metaphors) for sin and its effects, as vv. 11-12 make clear.

[53:4]  ² tn The words “for something he had done” are supplied in the translation for clarification. The group now realizes he suffered because of his identification with them, not simply because he was a special target of divine anger.

[13:7]  ³ sn Despite the NT use of this text to speak of the scattering of the disciples following Jesus’ crucifixion (Matt 26:31; Mark 14:27), the immediate context of Zechariah suggests that unfaithful shepherds (kings) will be punished by the Lord precisely so their flocks (disobedient Israel) can be scattered (cf. Zech 11:6, 8, 9, 16). It is likely that Jesus drew on this passage merely to make the point that whenever shepherds are incapacitated, sheep will scatter. Thus he was not identifying himself with the shepherd in this text (the shepherd in the Zechariah text is a character who is portrayed negatively).
