'Lowing' in the Bible

And the kine went straight forward on the way to Beth-shemesh; they went by the one high way, lowing as they went; and they turned not aside to the right hand or to the left; and the lords of the Philistines went after them as far as the border of Beth-shemesh.

And Samuel said, What means then this bleating of sheep in mine ears, and the lowing of oxen which I hear?
