 Amongst the Jews marriage was theoretically held in the highest esteem. It was said that a Jew must die rather than commit murder, idolatry or adultery. But, in fact, divorce was tragically easy. The Deuteronomic law laid it down that a man could divorce his wife if he found "some uncleanness" or "some matter of shame" in her. The difficulty was in defining what was a "matter of shame." The stricter Rabbis confined that to adultery alone; but there was a laxer teaching which widened its scope to include matters like spoiling the dinner by putting too much salt in the food; going about in public with her head uncovered; talking with men in the streets; speaking disrespectfully of her husband's parents in his presence; being a brawling woman (which was defined as a woman whose voice could be heard in the next house). It was only to be expected that the laxer view prevailed.
