7 “Ask and it will be given to you; seek and you will find; knock and the door will be opened for you. 8 For everyone who asks receives, and the one who seeks finds, and to the one who knocks, the door will be opened. 9 Is there anyone among you who, if his son asks for bread, will give him a stone? 10 Or if he asks for a fish, will give him a snake? 11 If you then, although you are evil, know how to give good gifts to your children, how much more will your Father in heaven give good gifts to those who ask him! 12 In everything, treat others as you would want them to treat you, for this fulfills the law and the prophets.
There was another incident involving one gentile who came before Shammai and said to Shammai: Convert me on condition that you teach me the entire Torah while I am standing on one foot. Shammai pushed him away with the builder’s cubit in his hand. This was a common measuring stick and Shammai was a builder by trade. The same gentile came before Hillel. He converted him and said to him: That which is hateful to you do not do to another; that is the entire Torah, and the rest is its interpretation. Go study.
