Exodus 2:4

And his sister stood afar off to wit what would be done with him. Miriam had thus reached an age at which she could volunteer to watch over the baby, to find out what would happen to him. The place chosen by the anxious mother was one frequented by the daughter of Pharaoh for bathing, and this fact entered into her plans. She trusted in the Lord that He would take care of her son, for faith will dare many things for the sake of a thing which has the approval of God.
