Gather yourselves together. — This rendering has little to recommend it. Two translations of the obscure verb here used are possible: Sift yourselves, yea sift — i.e., winnow out the sins which have roused Jehovah’s anger; or Bend yourselves, yea bend. We prefer the latter. The contumacious nation is exhorted to bend in submission to Jehovah before His judgment is revealed.
O nation not desired. — Better, O nation that art not abashed — scil. by God’s threats: the shameless defiant nation; so the 70, ἔθνος�.
