Job39:12 Will the ox of the mountains be your servant? or is his night's resting-place by your food-store?
Pro14:4 Where there are no oxen, their food-place is clean; but much increase comes through the strength of the ox.
Isa1:3 Even the ox has knowledge of its owner, and the ass of the place where its master puts its food: but Israel has no knowledge, my people give no thought to me.
