We present a secure redshift of z=0.944\pm0.002 for the lensed object in theEinstein ring gravitational lens B0218+357 based on five broad emission lines,in good agreement with our preliminary value announced several years ago basedsolely on the detection of a single emission line.Comment: Accepted for publication in the Ap
