Rahab was a woman of Jericho with a scandalous past, but she hid the Israelite spies and staked everything on the God of Israel — for the LORD your God, he is God in heaven above, and in earth beneath. A scarlet cord in her window spared her house when the city fell.
The New Testament honours her twice: Hebrews lists her among the heroes of faith — by faith the harlot Rahab perished not — and Matthew names her in the genealogy of Jesus. Her story is one of Scripture's clearest pictures of grace reaching the outsider.
Rahab is a bold, uncommon name carried by one of the Bible's great examples of saving faith.
Rachab, Rahaba
Rahab in the Bible
By faith the harlot Rahab perished not with them that believed not, when she had received the spies with peace.
