This remark appears in the form of a question to express the Jews' surprise that Jesus did not heal Lazarus. Alternate translation: "He could heal a man who was blind, so he should have been able to heal this man so he would not have died!" or "Since he did not keep this man from dying, maybe he did not really heal the man who was born blind, as they say he did!" (See: [[rc://en/ta/man/translate/figs-rquestion]])
