Hebrews 3:17-19 Young's Literal Translation (YLT)
17 but with whom was He grieved forty years? was it not with those who did sin, whose carcasses fell in the wilderness?
18 and to whom did He swear that they shall not enter into His rest, except to those who did not believe? --
19 and we see that they were not able to enter in because of unbelief.
Hebrews 3:17-19 New International Version (NIV)
17 And with whom was he angry for forty years? Was it not with those who sinned, whose bodies perished in the wilderness? 18 And to whom did God swear that they would never enter his rest if not to those who disobeyed? 19 So we see that they were not able to enter, because of their unbelief.
