Deut 6:4-13

Hear, O Israel: The Lord is our God, the Lord alone. You shall love the Lord your God with all your heart, and with all your soul, and with all your might. Keep these words that I am commanding you today in your heart. Recite them to your children and talk about them when you are at home and when you are away, when you lie down and when you rise. Bind them as a sign on your hand, fix them as an emblem on your forehead, and write them on the doorposts of your house and on your gates.

Caution against Disobedience

When the Lord your God has brought you into the land that he swore to your ancestors, to Abraham, to Isaac, and to Jacob, to give you—a land with fine, large cities that you did not build, houses filled with all sorts of goods that you did not fill, hewn cisterns that you did not hew, vineyards and olive groves that you did not plant—and when you have eaten your fill, take care that you do not forget the Lord, who brought you out of the land of Egypt, out of the house of slavery. The Lord your God you shall fear; him you shall serve, and by his name alone you shall swear.

Matthew 17:14-20

Jesus Cures a Boy with a Demon

When they came to the crowd, a man came to him, knelt before him, and said, ‘Lord, have mercy on my son, for he is an epileptic and he suffers terribly; he often falls into the fire and often into the water. And I brought him to your disciples, but they could not cure him.’ Jesus answered, ‘You faithless and perverse generation, how much longer must I be with you? How much longer must I put up with you? Bring him here to me.’ And Jesus rebuked the demon, and it came out of him, and the boy was cured instantly. Then the disciples came to Jesus privately and said, ‘Why could we not cast it out?’ He said to them, ‘Because of your little faith. For truly I tell you, if you have faith the size of a mustard seed, you will say to this mountain, “Move from here to there”, and it will move; and nothing will be impossible for you.’
