Jeremiah 17:4

and thou, even of thyself, shalt discontinue i.e. shalt cease to retain a hold upon thy country. We should rather read, and thou shalt let thine hand fall, adopting J. D. Michaelis's emendation, suggested by Deuteronomy 15:3, where the same Hebrew verb in immediate connexion with "thy hand" is used to indicate the cancelling of a debt. Du. and Co. needlessly reject this part of the v., for metrical reasons and as prosaic in expression.

I will cause thee to serve thine enemies So in all probability we should read in Jeremiah 15:14, according to the second of the alternative margins there.
