What does the Bible say about peace as a river?

In Isaiah 48:18, it is written, 'O that thou hadst hearkened to my commandments! Then had thy peace been as a river, and thy righteousness as the waves of the sea.' This passage illustrates that peace is contingent upon our response to God's commands. The lack of obedience leads to unrest, while hearkening to the divine call results in the abundance of peace, likened to a river that never runs dry. The context emphasizes that such peace is a gift from God, rooted in His grace, rather than something we attain through our efforts.
