• Joshua 9:3-13
  But when the inhabitants of Gibeon heard what Joshua had done to Jericho and Ai, they worked craftily, and went and pretended to be ambassadors. And they took old sacks on their donkeys, old wineskins torn and mended, old and patched sandals on their feet, and old garments on themselves; and all the bread of their provision was dry and moldy. And they went to Joshua, to the camp at Gilgal, and said to him and to the men of Israel, “We have come from a far country; now therefore, make a covenant with us.” Then the men of Israel said to the Hivites, “Perhaps you dwell among us; so how can we make a covenant with you?” But they said to Joshua, “We are your servants.” And Joshua said to them, “Who are you, and where do you come from?” So they said to him: “From a very far country your servants have come, because of the name of the LORD your God; for we have heard of His fame, and all that He did in Egypt, and all that He did to the two kings of the Amorites who were beyond the Jordan—to Sihon king of Heshbon, and Og king of Bashan, who was at Ashtaroth. Therefore our elders and all the inhabitants of our country spoke to us, saying, ‘Take provisions with you for the journey, and go to meet them, and say to them, “We are your servants; now therefore, make a covenant with us.”’ This bread of ours we took hot for our provision from our houses on the day we departed to come to you. But now look, it is dry and moldy. And these wineskins which we filled were new, and see, they are torn; and these our garments and our sandals have become old because of the very long journey.”

• Proverbs 6:12-15
  A worthless person, a wicked man,
  Walks with a perverse mouth;
  He winks with his eyes,
  He shuffles his feet,
  He points with his fingers;
  Perversity is in his heart,
  He devises evil continually,
  He sows discord.
  Therefore his calamity shall come suddenly;
  Suddenly he shall be broken without remedy.

• Proverbs 26:24-26
  He who hates, disguises it with his lips,
  And lays up deceit within himself;

  Though his hatred is covered by deceit,
  His wickedness will be revealed before the assembly.
