Zakharia 8:13

8:13 And it will come about that just as you (both Judah and Israel) were a curse to the nations, so I will save you and you will be a blessing. Do not be afraid! Instead, be strong!’

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; ¹ 

I will turn my hand against the insignificant ones.

[13:7]  ¹ 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).
