'Oxen' in the Bible

Behold, Saul came following the oxen out of the field; and Saul said, "What ails the people that they weep?" They told him the words of the men of Jabesh.

He took a yoke of oxen, and cut them in pieces, and sent them throughout all the borders of Israel by the hand of messengers, saying, "Whoever doesn't come forth after Saul and after Samuel, so shall it be done to his oxen." The dread of Yahweh fell on the people, and they came out as one man.
