There’s a principle showing the Gospels are reliable because they include details that no author would invent—embarrassing failures of the disciples, scandals, and brokenness. Matthew goes out of his way to highlight the flawed people in Jesus’ family tree. One of those is Rahab, remembered in Scripture as “Rahab the prostitute.” From this, we see that God’s holiness is not at odds with His mercy – He redeems people with labels, and their stories become part of His story.
