JOS 2:1

1 Then Joshua [chose] two men from [their camp at] Acacia. He told them, “Go [across the Jordan River] and secretly find out all that you can about the land on that side of the river, especially about Jericho [city].” So the two men crossed [the river and entered Jericho]. They entered the house of a prostitute, whose name was Rahab. They stayed in her house [that night].
