Hebrews 11:29-31
29 By faith the people crossed the Red Sea as on dry land, but the Egyptians, when they attempted to do the same, were drowned. 30 By faith the walls of Jericho fell down after they had been encircled for seven days. 31 By faith Rahab the prostitute did not perish with those who were disobedient, because she had given a friendly welcome to the spies.
