This is an unhappy expression, bringing in the name of God where it does not occur. In the O.T. it is chalilah, 'far be it.' Ge 44:7,17, etc. In the N.T. ?? ???????, 'let it not be.' Ro 3:4,6,31, etc.
They said to him, "Why does my lord speak such words as these? Far be it from your servants that they should do such a thing!
He said, "Far be it from me that I should do so. The man in whose hand the cup is found, he will be my bondservant; but as for you, go up in peace to your father."
May it never be! Yes, let God be found true, but every man a liar. As it is written, "That you might be justified in your words, and might prevail when you come into judgment."
May it never be! For then how will God judge the world?
Do we then nullify the law through faith? May it never be! No, we establish the law.
