Psalm 78:42
They remembered not his hand, nor the day when he delivered them from the enemy.
They remembered not his hand,.... Which brought them out of Egypt, and dashed their enemies in pieces, and which had been so often opened to supply their wants in the wilderness; the Targum renders it, the miracles of his hand:
nor the day when he delivered them from the enemy; Pharaoh king of Egypt; that very memorable day in which they were delivered out of his hands, that selfsame day which had been fixed, by promise and prophecy many hundreds of years before, in which the hosts of the Lord went out of Egypt, Exodus 12:41, times when as well as places where deliverances and salvation have been wrought should not be forgotten; and forgetfulness of the goodness of God in times past is often the cause and occasion of sinning against him, which, by a remembrance of his kind appearances, might be prevented.
