Exodus 2:23 (NKJV) Now it happened in the process of time that the king of Egypt died. Then the children of Israel groaned because of the bondage, and they cried out; and their cry came up to God because of the bondage.
In this scripture “the king of Egypt” was symbolic of a force that had control over the children of Israel. The bondage represented here was a “generational” bondage. Once the strongman aka king of Egypt died, the cries of those in bondage reaches the ears of God.
Whatever your bondage is or the one you are praying for, bind the strongman of that sin and your cries will reach the ears of God.
