"You are the light of the world. A city set on a hill cannot be hidden; nor does anyone light a lamp and put it under a basket, but on the lampstand, and it gives light to all who are in the house.
Let your light shine before men in such a way that they may see your good works, and glorify your Father who is in heaven.
Do not think that I came to violate the Torah or the Prophets; I did not come to violate but to uphold. For, amen, I say to you, until heaven and earth pass away, not the smallest letter or stroke shall pass from the Torah until all is accomplished. Whoever then violates one of the least of these commandments, and teaches others to do the same, shall be called least in the kingdom of heaven; but whoever keeps and teaches them, he shall be called great in the kingdom of heaven. For I say to you that unless your righteous acts surpass that of the scribes and Pharisees, you will not enter the kingdom of heaven."
This is the teaching of the Rabbi.
