Zechariah 2:8

2:8 For the Lord who rules over all says to me that for his own glory he has sent me to the nations that plundered you – for anyone who touches you touches the pupil of his eye.

Zechariah 9:8

9:8 Then I will surround my temple to protect it like a guard from anyone crossing back and forth; so no one will cross over against them anymore as an oppressor, for now I myself have seen it.
