‘And he who blasphemes the Name of יהוה shall certainly be put to death, and all the congregation certainly stone him, the stranger as well as the native. When he blasphemes the Name, he is put to death.
If anyone sees his brother sinning a sin, not unto death, he shall ask, and He shall give him life for those not sinning unto death. There is a sin unto death. I do not say that he should pray about that.
