Exodus 10:2

That thou mayest tell. A new objective of the plagues is now revealed. They were designed not only to impress Pharaoh and his servants with the greatness of God and to secure his cooperation, but to convince the children of Israel for all future generations that the Lord is the only true God. Psalms 78, 105, and 106 illustrate how the story of deliverance was handed down from generation to generation. It was God’s plan that His mercies and wondrous works be kept in perpetual remembrance. His proneness to forget God’s benefits being one of the sad facets of his sinful character, man requires constant exhortation to remember them. This is often true of his daily needs, but applies also to providential circumstances, such as those connected with conversion or recovery from severe illness.
