'Astray' in the Bible

Then I said, “I will no longer shepherd you. Let what is dying die, and let what is going astray go astray; let the rest devour each other’s flesh.”

I am about to raise up a shepherd in the land who will not care for those who are going astray, and he will not seek the lost or heal the broken. He will not sustain the healthy, but he will devour the flesh of the fat sheep and tear off their hooves.
