'Oxen' in the Bible

"A second pleaded, "'I have bought five yoke of oxen, and am on my way to try them. Pray hold me excused.'

Is God simply thinking about the oxen? Or is it really in our interest that He speaks? Of course, it was written in our interest, because it is His will that when a plough-man ploughs, and a thresher threshes, it should be in the hope of sharing that which comes as the result.

Do not come into close association with unbelievers, like oxen yoked with asses. For what is there in common between righteousness and lawlessness? Or what partnership has light with darkness?
