Now the promises were made to Abraham and to his descendant. It does not say, "And to descendants," as referring to many, but as referring to one, "And to your descendant," who is Christ. This is what I mean: the law, which came four hundred and thirty years afterward, does not annul a covenant previously ratified by God, so as to cancel the promise. For if the inheritance comes from the law, it is no longer from a promise; but God bestowed it on Abraham through a promise. Why, then, the law? It was added for transgressions, until the descendant came to whom the promise had been made; it was promulgated by angels at the hand of a mediator. Now there is no mediator when only one party is involved, and God is one. Is the law then opposed to the promises (of God)? Of course not! For if a law had been given that could bring life, then righteousness would in reality come from the law. But scripture confined all things under the power of sin, that through faith in Jesus Christ the promise might be given to those who believe.
As he continued his journey to Jerusalem, he traveled through Samaria and Galilee. As he was entering a village, ten lepers met (him). They stood at a distance from him and raised their voice, saying, "Jesus, Master! Have pity on us!" And when he saw them, he said, "Go show yourselves to the priests." As they were going they were cleansed. And one of them, realizing he had been healed, returned, glorifying God in a loud voice; and he fell at the feet of Jesus and thanked him. He was a Samaritan. Jesus said in reply, "Ten were cleansed, were they not? Where are the other nine? Has none but this foreigner returned to give thanks to God?" Then he said to him, "Stand up and go; your faith has saved you.".
