. The oxen is good but it is not a mate for man. The sheep is good but it is not a mate for man. The mate for man is woman and that is the cross man must bear
Here woman is categorised as a species that is separated from men and is compared to animals such as oxen and sheep -- one symbolises immense strength and fertility, and for the other, obedience -- and most importantly, they are both tamed domestic animals. To place woman in between those two animals is to point out the social expectation of the so-called qualities/societal function that women should have, the ability to fertilise, and to obey, and to serve with their sexuality. It is obviously said in the sarcastic way from a patriarchal viewpoint, but powerful indeed.
