Matthew 7:6-9 (New International Version)

 ⁶"Do not give dogs what is sacred; do not throw your pearls to pigs. If you do, they may trample them under their feet, and then turn and tear you to pieces.

Ask, Seek, Knock

 ⁷"Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. ⁸For everyone who asks receives; he who seeks finds; and to him who knocks, the door will be opened.

 ⁹"Which of you, if his son asks for bread, will give him a stone?
