Dishonesty being contrary to the principles of Christianity, it's rather difficult to credit.
Yup:
Exodus 20: 16 "You shall not give false testimony against your neighbor.
also...
Deuteronomy 5:20 "You shall not give false testimony against your neighbor.
There's also these:
NIV Joshua 2:1-6
1. Then Joshua son of Nun secretly sent two spies from Shittim. "Go, look over the land," he said, "especially Jericho." So they went and entered the house of a prostitute named Rahab and stayed there.
2. The king of Jericho was told, "Look! Some of the Israelites have come here tonight to spy out the land."
3. So the king of Jericho sent this message to Rahab: "Bring out the men who came to you and entered your house, because they have come to spy out the whole land."
4. But the woman had taken the two men and hidden them. She said, "Yes, the men came to me, but I did not know where they had come from.
5. At dusk, when it was time to close the city gate, the men left. I don't know which way they went. Go after them quickly. You may catch up with them." <-- Big, Fat LIE!!!!
6. (But she had taken them up to the roof and hidden them under the stalks of flax she had laid out on the roof.)
NIV Joshua 6:17
The city and all that is in it are to be devoted to the LORD. Only Rahab the prostitute and all who are with her in her house shall be spared, because she hid the spies we sent.
NIV Joshua 6:23
So the young men who had done the spying went in and brought out Rahab, her father and mother and brothers and all who belonged to her. They brought out her entire family and put them in a place outside the camp of Israel.
NIV Joshua 6:25
But Joshua spared Rahab the prostitute, with her family and all who belonged to her, because she hid the men Joshua had sent as spies to Jericho--and she lives among the Israelites to this day.

5. Salmon the father of Boaz, whose mother was Rahab, Boaz the father of Obed, whose mother was Ruth, Obed the father of Jesse,

NIV Hebrews 11:31
By faith the prostitute Rahab, because she welcomed the spies, was not killed with those who were disobedient.
NIV James 2:25
In the same way, was not even Rahab the prostitute considered righteous for what she did when she gave lodging to the spies and sent them off in a different direction?
Now.... what was your point again??
