Luke 2: 16 - 21
16 And they went with haste, and found Mary and Joseph, and the babe lying in a manger.
17 And when they saw it they made known the saying which had been told them concerning this child;
18 and all who heard it wondered at what the shepherds told them.
19 But Mary kept all these things, pondering them in her heart.
20 And the shepherds returned, glorifying and praising God for all they had heard and seen, as it had been told them.
21 And at the end of eight days, when he was circumcised, he was called Jesus, the name given by the angel before he was conceived in the womb.
