1 Kings 17:4 - Wesley's Explanatory Notes

Have commanded — Or, I shall command, that is, effectually move them, by instincts which shall be as forcible with them, as a law or command is to men. God is said to command both brute creatures, and senseless things; when he causeth them to do the things which he intends to effect by them. The ravens — Which he chuseth for this work; to shew his care and power in providing for the prophet by those creatures, which are noted for their greediness, that by this strange experiment he might be taught to trust God in those many and great difficulties to which he was to be exposed. God could have sent angels to minister to him. But he chose winged messengers of another kind to shew he can serve his own purposes as effectually, by the meanest creatures as by the mightiest. Ravens neglect their own young, and do not feed them: yet when God pleaseth, they shall feed his prophet.
