Zechariah 11:5

11:5 Those who buy them ¹  slaughter them and are not held guilty; those who sell them say, ‘Blessed be the Lord, for I am rich.’ Their own shepherds have no compassion for them.

Zechariah 13:9

13:9 Then I will bring the remaining third into the fire;

I will refine them like silver is refined

and will test them like gold is tested.

They will call on my name and I will answer;

I will say, ‘These are my people,’

and they will say, ‘The Lord is my God.’” ² 

[11:5]  ¹ sn The expression those who buy them appears to be a reference to the foreign nations to whom Israel’s own kings “sold” their subjects. Far from being good shepherds, then, they were evil and profiteering. The whole section (vv. 4-14) refers to the past when the Lord, the Good Shepherd, had in vain tried to lead his people to salvation and life.

[13:9]  ² sn The expression I will say ‘It is my people,’ and they will say ‘the Lord is my God’ is reminiscent of the restoration of Israel predicted by Hosea, who said that those who had been rejected as God’s people would be reclaimed and once more become his sons and daughters (Hos 2:23).
