Charles Ellicott Commentary Amos 3:12

"Thus saith Jehovah: As the shepherd rescueth out of the mouth of the lion two legs, or a piece of an ear, so shall the children of Israel be rescued that sit in Samaria in the corner of a couch, and on the silken cushions of a bed." — Amos 3:12 (ASV)

Takes out ... taken out.— This should be (as in the margin) delivers ... be delivered. The agricultural image, used by Amos, is very impressive. The shanks and pieces of the ear, worthless portions, saved from the lion’s jaws, represent the remnants of Samaria’s population that shall escape.

In Damascus in a couch.— Some would render “in Damascus on that of (i.e., corner of) a couch,” Damascus corresponding to Samaria in the parallel clause. But this construction is very questionable, and it would be much simpler and safer to adopt the reading of most Hebrew texts, and render on a couch’s damask (so Gesenius and Ewald), referring to the silken (?) or white woollen fabric for which Damascus, even in that early age, was famous. The relations between Syria and Israel at this moment were intimate. The meaning is that even the noblest and wealthiest will be regarded, if saved, as worthless salvage.
