Joshua 2:19
And it shall be, that whosoever shall go out of the doors of thy house into the street, his blood shall be upon his head, and we will be guiltless: and whosoever shall be with thee in the house, his blood shall be on our head, if any hand be upon him.
Joshua 2:19 belongs to the account of Rahab, a Canaanite living among an idolatrous people. She turned away from idolatry to worship the true God. In doing so she joined His people and cast her lot with Israel. Her example shows that people from other nations who turned to God were to be welcomed among Israel.
