Mark 10:10

And in the house the disciples asked him again of this matter, and he saith unto them, Whosoever shall put away his wife and marry another, committeth adultery against her: And if she herself shall put away her husband, and marry another, she committeth adultery.

To divorce one's wife and marry another is to break the seventh commandment; and the rule applies with equal force to putting away one's husband and marrying another. This pronouncement of Jesus went far beyond anything the Jews taught.

According to Rabbinic law, a husband could not be said to commit adultery against his wife. So Jesus goes beyond Rabbinic teaching by speaking of a husband's committing adultery against his wife.[13]

Mark's record of Jesus' application of the rule on adultery to both sexes is thought to have been prompted by Gentile readers to whom this gospel is supposed to have been directed. The view here is that Christ spoke all that is recorded of him, both here and in the other gospels; and the fact of one writer's having recorded one thing and another's having recorded different things (though not contradictory) is due to the difference of intention and purpose that each had. This means that the total of Jesus' teaching must be determined by the composite record of all the gospels. Such a view is in line with what Jesus himself said regarding the belief of "all that the prophets have spoken" (Luke 24:25).
