Thus saith the LORD; As the shepherd taketh out of the mouth of the lion two legs, or a piece of an ear; so shall the children of Israel be taken out that dwell in Samaria in the corner of a bed, and in Damascus in a couch.

They say to the people: "Journey over to Calneh and look at it! Then go from there to Hamath-Rabbah! Then go down to Gath of the Philistines! Are they superior to our two kingdoms? Is their territory larger than yours?"

Getting the poor for silver, and him who is in need for the price of two shoes, and taking a price for the waste parts of the grain.
