Adam Clarke on Exodus 2:7

Shall I go and call a nurse - Had not the different circumstances marked here been placed under the superintendence of an especial providence, there is no human probability that they could have had such a happy issue. The parents had done every thing to save their child that piety, affection, and prudence could dictate, and having done so, they left the event to God. By faith, says the apostle, Heb 11:23, Moses, when he was born, was hid three months of his parents, because they saw he was a proper child; and they were not afraid of the king's commandment. Because of the king's commandment they were obliged to make use of the most prudent caution to save the child's life; and their faith in God enabled them to risk their own safety, for they were not afraid of the king's commandment - they feared God, and they had no other fear.
