Zechariah 11:5

11:5 Those who buy them 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.

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.
