LORD, in trouble have they visited thee, they poured out a prayer when thy chastening was upon them. Lord, in trouble have they visited thee "O Jehovah, in affliction we have sought thee" - So the Septuagint and two MSS. have פקדנוך pekadnucha, in the first person plural. And so perhaps it should be צקנו tsaknu, in the first person; but how the Septuagint read this word is not clear; and this last member of the verse is extremely obscure.
For למו lamo, "on them," the Septuagint read לנו lanu, "on us," in the first person likewise; a frequent mistake; see note on Isaiah 10:29.
