Rahab, Woman of Jericho

Some biblical scholars maintain that the woman in Jericho who hid Joshua's two spies was a harlot or a prostitute. But if that was the case, how did this woman, Rahab, become one of the ancestors of Jesus Christ? Wouldn't the Father ensure a pure lineage for His Son?  
Author Diana Wallis Taylor offers a beautiful story of intrigue that explains how Rahab came to be the mother of Boaz, grandmother of Obed, and great-grandmother of Jesse, the father of King David.  
In *Rahab, Woman of Jericho*, readers discover a Rahab who is a descendent of the tribe of Ephraim, one of the ten lost tribes of Israel. Her clan left Egypt and settled in Canaan before the Hebrews were enslaved. Although they did not wander in the desert with Moses for forty years, nor did they hear the laws that the Lord gave to His people, they still worshipped the one true God.  
Rahab marries Radames, a young Egyptian officer, who is to become the new governor of Jericho. They live in the Egyptian embassy set in the city wall*.* When the Israelites approach Canaan with their army, pharaoh sends word that he is withdrawing his troops. Radames fabricates a story to tell Jericho's king, but Hammurabi doesn't believe it...and he has his eye on the beautiful Rahab.  
What will happen to Rahab after the lecherous king poisons her husband? How can she save her family from the invading Israelites? God parted the waters of the Jordan River for them--will He likewise provide miracles and blessings to her Ephraimite clan if they can rejoin their people?Read less
