Ambrose of Milan, on Prov 21:1

“As the divisions of waters, so the heart of the king is in the hand of the Lord: whithersoever he will he shall turn it.”

“Entrust your soul to the hands of the Lord. Not only when it departs from the body but also when it is in the body, it is in the hands of the Lord, because you do not see it, its source or its destination. It is both in you and also with God. Therefore "the heart of the king is in the hand of the Lord," who guides it and rules it. The heart is also filled with the spirit, because the spirit is the ruling part of the soul and the strength of the soul. I say that strength lies not in the arms but in counsel, temperance, piety and justice. If the heart of a man is in the hand of the Lord, much more is his soul.”
