St. Paul's Letter to the Galatians 4:22-27
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."
Matthew 14:22-34 9th Sunday of Matthew
At that time, Jesus made the disciples get into the boat and go before him to the other side, while he dismissed the crowds. And after he had dismissed the crowds, he went up into the hills by himself to pray. When evening came, he was there alone, but the boat by this time was many furlongs distant from the land, beaten by the waves; for the wind was against them. And in the fourth watch of the night he came to them, walking on the sea. But when the disciples saw him walking on the sea, they were terrified, saying, "It is a ghost!" And they cried out for fear. But immediately he spoke to them, saying "Take heart, it is I; have no fear."
And Peter answered him, "Lord, if it is you, bid me come to you on the water." He said, "Come." So Peter got out of the boat and walked on the water and came to Jesus; but when he saw the wind, he was afraid, and beginning to sink he cried out, "Lord, save me." Jesus immediately reached out his hand and caught him, saying to him, "O man of little faith, why did you doubt?" And when they entered the boat, the wind ceased. And those in the boat worshiped him, saying, "Truly you are the Son of God." And when they had crossed over, they came to land at Gennesaret.
