John 5:31

“If I bear witness of myself, etc.] Which was not allowed any man to do; nor indeed is it proper that a man should be a witness in his own cause: and, according to the Jewish canons, a man might not be a witness for his wife, because she was reckoned as himself. “An husband is not to be believed in bearing witness for his wife, that had been carried captive, that she is not defiled, wmx[l dy[m µda ˆyaç, “for no man witness of himself” f248.” So likewise they say f249, “a city that is subdued by an army, all the priestesses (or priests’ daughters) that are found in it are rejected (from the priesthood, as defiled); but if they have witnesses, whether a servant, or an handmaid, lo, they are to…”

Though what Jesus said was true John 8:13, John 8:17, yet he admitted it was not sufficient testimony alone to claim their belief. They had a right to expect that his…”
