1And Abram’s wife Sarai had not given birth by him. And she had an Egyptian maid, and her name was Hagar.
2And Sarai said to Abram, “Here, YHWH has held me back from giving birth. Come to my maid. Maybe I’ll get ‘childed’ through her.” And Abram listened to Sarai’s voice.
3And Sarai, Abram’s wife, took Hagar, the Egyptian, her maid, at the end of ten years of Abram’s living in the land of Canaan, and gave her to Abram, her husband, as a wife to him.
4And he came to Hagar, and she became pregnant. And she saw that she had become pregnant, and her mistress was lowered in her eyes.
5And Sarai said to Abram, “My injury is on you. I, I, placed my maid in your bosom, and she saw that she had become pregnant, and I was lowered in her eyes. Let YHWH judge between me and you.”
6And Abram said to Sarai, “Here, your maid is in your hand. Do to her whatever is good in your eyes.” And Sarai degraded her, and she fled from her.
16:6. And Sarai degraded her, and she fled. Sarai’s treatment of the Egyptian Hagar foreshadows (or is reversed in, or governs) Israel’s experience in Egypt. These exact words recur there: Egypt degraded them (Exod 1:12), and they fled (14:5). And note that, like Israel, Hagar fled to the wilderness (v. 7)
7And an angel of YHWH found her at a spring of water in the wilderness, by the spring on the way to Shur,
8and said, “Hagar, Sarai’s maid, from where have you come, and where will you go?”
And she said, “I’m fleeing from Sarai, my mistress.”
9And the angel of YHWH said to her, “Go back to your mistress, and suffer the degradation under her hands.”
10And the angel of YHWH said, “I’ll multiply your seed, and it won’t be countable because of its great number.”
11And the angel of YHWH said to her, “Here, you’re pregnant and will give birth to a son, and you shall call his name Ishmael, for YHWH has listened to your suffering.
12And he’ll be a wild ass of a man, his hand against everyone, and everyone’s hand against him, and he’ll tent among all his brothers.”
16:12. he’ll tent. The verb is denominative; that is, the verb “to tent” (Hebrew root škn) derives from the word mišk
n, a tent or tabernacle. In the blessing of Noah’s son Yaphet, it refers explicitly to dwelling in tents (Gen 9:27). In Moses’ blessing of Benjamin (Deut 33:12) it is connected to God’s “sheltering” (Hebrew 
p
p, related to upph, a canopy). Most important, it will be used (in its Piel form) for the way in which God tents the Ark of the Testimony inside the Tabernacle. Occasionally it can refer to “dwelling” in general, not necessarily in tents (e.g., Gen 49:13).
13And she called the name of YHWH who spoke to her “You are El-roi,” for she said, “Have I also seen after the one who sees me here?”
14On account of this the well was called “the well Lahai-roi.” Here it is between Kadesh and Bered.
15And Hagar gave birth to a son for Abram, and Abram called the name of his son whom Hagar had borne Ishmael.
16And Abram was eighty years and six years old when Hagar gave birth to Ishmael for Abram.
