Exodus 14:15

Wherefore criest thou to me? Moses, though he was assured of a good issue, yet did not neglect prayer. We read not of one word he said in prayer, but he lifted up his heart to God, and God well understood, and took notice of it. Moses's silent prayer prevailed more with God than Israel's loud outcries. But is God displeased with Moses for praying? No; he asks this question, Wherefore criest thou unto me? Wherefore shouldest thou press thy petition any further, when it is already granted? Moses has something else to do besides praying; he is to command the hosts of Israel. Speak to them that they go forward Some think Moses had prayed not so much for their deliverance, he was assured of that, as for the pardon of their murmurings: and God's ordering them to go forward was an intimation of the pardon. Moses bid them stand still and expect orders from God: and now orders are given. They thought they must have been directed either to the right hand or to the left; no, saith God, speak to them to go forward directly to the sea-side; as if there had lain a fleet of transport ships ready for them to embark in. Let the children of Israel go as far as they can upon dry ground, and then God will divide the sea. The same power could have congealed the waters for them to pass over, but infinite Wisdom chose rather to divide the waters for them to pass through, for that way of salvation is always pitched upon which is most humbling.
