Who was Hagar?
In the Hebrew Bible or Christian Old Testament, Hagar was an Egyptian woman, the handmaid or slave of Sarai; a present, perhaps, from Pharaoh when Abram dissembled to him in Egypt (Genesis 12:16). Mention is made of her in two passages (Gen 16; 21:8-21).
The Handmaid and Her Flight
In the first narrative (Gen 16) it is related that Sarai, despairing at her age of having children, gave Hagar to Abram as a concubine. As Hagar was not an ordinary household slave but the peculiar property of her mistress (compare Gen 29:24,29), any offspring which she might bear to Abram would be reckoned as Sarai's (compare Gen 30:3-9).
In the prospect of becoming a mother, Hagar, forgetting her position, seems to have assumed an insolent bearing toward her childless mistress. Sarai felt keenly the contempt shown her by her handmaid, and in angry tones brought her conduct before Abram.
Now that her plan was not working out smoothly, she unfairly blamed her husband for what originated with herself, and appealed to Heaven to redress her grievance. Abram refused to interfere in the domestic quarrel, and renouncing his rights over his concubine, and her claims on him, put her entirely at Sarai's disposal. Under the harsh treatment of her mistress Hagar's life became intolerable, and she fled into the wilderness, turning her steps naturally toward Egypt, her native land.
Her Vision and Return
But the angel of Yahweh (who is here introduced for the first time as the medium of theophany) appeared to her as she was resting by a spring and commanded her to return and submit herself to her mistress, promising her an innumerable seed through her unborn son, concerning whom he uttered a striking prediction.
To the angel (who is now said to be Yahweh Himself) Hagar gave the name "Thou art a God of seeing" (the Revised Version (British and American) "that seeth"), for she said, "Have I even here (in the desert where God, whose manifestations were supposed to be confined to particular places, might not be expected to reveal Himself) looked after him that seeth me?"--the meaning being that while God saw her, it was only while the all-seeing God in the person of His angel was departing that she became conscious of His presence.
The spring where the angel met with her was called in Hebrew tradition Be'er-lachay-ro'i, "the well of the living one who seeth me" (Revised Version, margin).
Obedient to the heavenly vision Hagar returned, as the narrative implies, to her mistress and gave birth to Ishmael, Abram being then eighty-six years old.
The idea in 30:13 is not very clearly expressed. The word translated "here" generally means "hither," and there is no explanation of the "living one" in the name of the well. It has therefore been proposed to emend the Hebrew text and read "Have I even seen God, and lived after my seeing?"--an allusion to the belief that no one could "see God and live" (compare Gen 32:30; Ex 33:20).
But there are difficulties in the way of accepting this emendation. The name of God, "a God of seeing," would require to be interpreted in an objective sense as "a God who is seen," and the consequent name of the well, "He that seeth me liveth," would make God, not Hagar, as in 30:13, the speaker.
Her Harsh Expulsion and Divine Help
The other narrative (Gen 21:8-21) relates what occurred in connection with the weaning of Isaac. The presence and conduct of Ishmael during the family feast held on the occasion roused the anger and jealousy of Sarah who, fearing that Ishmael would share the inheritance with Isaac, peremptorily demanded the expulsion of the slave-mother and her son.
But the instincts of Abraham's fatherly heart recoiled from such a cruel course, and it was only after the revelation was made to him that the ejection of Hagar and her son would be in the line of the Divine purpose--for Isaac was his real seed, while Ishmael would be made a nation too--that he was led to forego his natural feelings and accede to Sarah's demand.
So next morning the bondwoman and her son were sent forth with the bare provision of bread and a skin of water into the wilderness of Beersheba. When the water was spent, Hagar, unable to bear the sight of her boy dying from thirst, laid him under a shrub and withdrew the distance of a bowshot to weep out her sorrow. But the angel of God, calling to her out of heaven, comforted her with the assurance that God had heard the voice of the lad and that there was a great future before him.
Then her eyes were opened to discover a well of water from which she filled the skin and gave her son to drink. With God's blessing the lad grew up amid the desert's hardships, distinguished for his skill with the bow. He made his home in the wilderness of Paran, and his mother took a wife for him out of her own country.
