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 5:6

5:6 I asked, “What is it?” And he replied, “It is a basket for measuring grain that is moving away from here.” Moreover, he said, “This is their ‘eye’ throughout all the earth.”
