The Magnificat antiphon for I Vespers however, is actually from I Mac 6:39, which deals with the defense of the city from an attack by King Lysias, and the heroic death of Eleazar, who is crushed by an elephant in an effort to kill the king.
Lauds and Vespers: The canticle antiphons for this Sunday refer to the Sunday Gospel, John 4: 46-53 (Jesus heals the son of an official). At Lauds the Benedictus antiphon is as follows:
"There was a certain royal official whose son was sick at Capernaum. When he heard that Jesus was come into Galilee, he besought Him that He would heal his son."
The antiphon for the Magnificat at Vespers:
"The father knew then that it was at the same hour in the which Jesus said thy son lives. And himself believed, and his whole house."
