Brethren, Abraham had two sons, one by a slave and one by a free woman. But the son of the slave was born according to the flesh, the son of the free woman through promise. Now this is an allegory: these women are two covenants. One is from Mount Sinai, bearing children for slavery; she is Hagar. Now Hagar is Mount Sinai in Arabia; she corresponds to the present Jerusalem, for she is in slavery with her children. But the Jerusalem above is free, and she is our mother. For it is written, "Rejoice, O barren one who does not bear; break forth and shout, you who are not in travail; for the children of the desolate one are many more than the children of her that is married."

At that time, as Jesus was standing by the lake of Gennesaret, he saw two boats by the lake; but the fishermen had gone out of them and were washing their nets. Getting into one of the boats, which was Simon's, he asked him to put out a little from the land. And he sat down and taught the people from the boat. And when he had ceased speaking, he said to Simon, "Put out into the deep and let down your nets for a catch." And Simon answered, "Master, we toiled all night and took nothing! But at your word I will let down the nets." And when they had done this, they enclosed a great shoal of fish; and as their nets were breaking, they beckoned to their partners in the other boat to come and help them. And they came and filled both the boats, so that they began to sink. But when Simon Peter saw it, he fell down at Jesus' knees, saying, "Depart from me, for I am a sinful man, O Lord." For he was astonished, and all who were with him, at the catch of fish which they had taken; and so also were James and John, sons of Zebedee, who were partners with Simon. And Jesus said to Simon, "Do not be afraid; henceforth you will be catching men." And when they had brought their boats to land, they left everything and followed him.
