Thematic Bible: Testimoney

"And I also have a question to ask *you*," replied Jesus, "and if you answer me, I in turn will tell you by what authority I do these things. John's Baptism, whence was it? --had it a heavenly or a human origin?" So they debated the matter among themselves.

And they, when they had heard his statement, gave the glory to God. Then they said, "You see, brother, how many tens of thousands of Jews there are among those who have accepted the faith, and they are all zealous upholders of the Law. Now what they have been repeatedly told about you is that you teach all the Jews among the Gentiles to abandon Moses, and that you forbid them to circumcise their children or observe old-established customs. What then ought you to do? They are sure to hear that you have come to Jerusalem; so do this which we now tell you. We have four men here who have a vow resting on them. Associate with these men and purify yourself with them, and pay their expenses so that they can shave their heads. Then everybody will know that there is no truth in these stories about you, but that in your own actions you yourself scrupulously obey the Law. But as for the Gentiles who have accepted the faith, we have communicated to them our decision that they are carefully to abstain from anything sacrificed to an idol, from blood, from what is strangled, and from fornication."
