Brethren, to give a human example: no one annuls even a man's covenant, or adds to it, once it has been ratified. Now the promises were made to Abraham and to his offspring. It does not say, "And to your offsprings," referring to many; but, referring to one, "And to your offspring," which 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 make the promise void. For if the inheritance is by the law, it is no longer by promise; but God gave it to Abraham by a promise. Why then the law? It was added because of transgressions, till the offspring should come to whom the promise had been made; and it was ordained by angels through an intermediary. Now an intermediary implies more than one; but God is one. Is the law then against the promises of God? Certainly not; for if a law had been given which could make alive, then righteousness would indeed be by the law. But the scripture consigned all things to sin, that what was promised to faith in Jesus Christ might be given to those who believe.

At that time, Jesus called to him his twelve disciples and began to send them out two by two, and gave them authority over the unclean spirits. He charged them to take nothing for their journey except a staff; no bread, no bag, no money in their belts; but to wear sandals and not put on two tunics. And he said to them, "Where you enter a house, stay there until you leave the place. And if any place will not receive you and they refuse to hear you, when you leave, shake off the dust that is on your feet for a testimony against them." So they went out and preached that men should repent. And they cast out many demons, and anointed with oil many that were sick and healed them.
