Now when these words came to their ears their hearts were troubled, and they said to Peter and the other Apostles, Brothers, what are we to do?

And Peter said, Let your hearts be changed, every one of you, and have baptism in the name of Jesus Christ, for the forgiveness of your sins; and you will have the Holy Spirit given to you.

And day by day, going in agreement together regularly to the Temple and, taking broken bread together in their houses, they took their food with joy and with true hearts,

But he was not without witness, because he did good, and gave you rain from heaven and times of fruit, making your hearts full of food and joy.

And God, the searcher of hearts, was a witness to them, giving them the Holy Spirit even as he did to us;

Making no division between them and us, but making clean their hearts by faith.

For the effecting of which our twelve tribes have been working and waiting night and day with all their hearts. And in connection with this hope I am attacked by the Jews, O king!

For the heart of this people has become fat and their ears are slow in hearing and their eyes are shut; for fear that they might see with their eyes and give hearing with their ears and become wise in their hearts and be turned again to me, so that I might make them well.
