The bible is pretty clear on observing the Sabbath, so clear that it is the 4th commandment. Exodus 31:14 tells us exactly about the consequences of breaking this law by “every one” and whosoever” , meaning no exception. John 5:18, Matthew 12:1 are first hand written testimonies that Jesus broke this law. Numbers 15:32-36 showed how God dealt with people who break the Sabbath.
And that’s not all from Jesus. Any question?
