'Lost' in the Bible

I will take the blood from their mouthsAnd their detestable things from between their teeth [those repulsive, idolatrous sacrifices eaten with the blood].Then they too will be a remnant for our God,And be like a clan in Judah,And Ekron will be like one of the Jebusites.

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.
