John Wesley on Exodus 9:6

All the cattle died - All that were in the field. The creature is made subject to vanity by the sin of man, being liable, according to its capacity, both to serve his wickedness, and to share in his punishment. The Egyptians worshipped their cattle; it was among them that the Israelites learned to make a god of a calf; in that therefore this plague meets with them. But not one of the cattle of the Israelites died - Doth God take care for oxen? Yes, he doth, his providence extends itself to the meanest of his creatures.
