Joshua 2:12
Now therefore, I pray you, swear unto me by the LORD, since I have showed you kindness, that ye will also show kindness unto my father's house, and give me a true token:
Joshua 5:6
For the children of Israel walked forty years in the wilderness, till all the people that were men of war, which came out of Egypt, were consumed, because they obeyed not the voice of the LORD: unto whom the LORD sware that he would not show them the land, which the LORD sware unto their fathers that he would give us, a land that floweth with milk and honey.
