‘ And the king of Jericho sent to Rahab, saying, “Bring out the men who have come to you, which have entered your house, for they are come to search out the whole land.” '
The king, a petty kinglet of a small city, immediately sent Rahab a message, no doubt for her ears alone, telling her to arrange for the visitors to be seized and brought to the king. Indeed the messengers were even then almost certainly outside the house waiting to arrest them.
“Who have come to you, which have entered your house.” Such repetition occurs regularly in ancient literature. While unnecessary in reading, it assists a hearer to take in the story, become a part of it and remember the details as the story unfolds. A listener is not able to check back on the facts.
