This reading is from the portion read on the first day of Rosh Hashanah, which falls on September 27 this year.
Early next morning Abraham took some bread and a skin of water, and gave them to Hagar. He placed them over her shoulder, together with the child, and sent her away. And she wandered about in the wilderness of Beer-sheba. When the water was gone from the skin, she left the child under one of the bushes, and went and sat down at a distance, a bowshot away; for she thought, "Let me not look on as the child dies." And sitting thus afar, she burst into tears.
God heard the cry of the boy, and an angel of God called to Hagar from heaven and said to her, "What troubles you, Hagar? Fear not, for God has heeded the cry of the boy where he is. Come, lift up the boy and hold him by the hand, for I will make a great nation of him." Then God opened her eyes and she saw a well of water. She went and filled the skin with water, and let the boy drink. God was with the boy and he grew up; he dwelt in the wilderness and became a bowman. He lived in the wilderness of Paran; and his mother got a wife for him from the land of Egypt.
