Hagar

flight, or, according to others, stranger, an Egyptian, Sarah's
handmaid (Gen. 16:1; 21:9, 10), whom she gave to Abraham (q.v.)
as a secondary wife (16:2). When she was about to become a
mother she fled from the cruelty of her mistress, intending
apparently to return to her relatives in Egypt, through the
desert of Shur, which lay between. Wearied and worn she had
reached the place she distinguished by the name of
Beer-lahai-roi ("the well of the visible God"), where the angel
of the Lord appeared to her. In obedience to the heavenly
visitor she returned to the tent of Abraham, where her son
Ishmael was born, and where she remained (16) till after the
birth of Isaac, the space of fourteen years. Sarah after this
began to vent her dissatisfaction both on Hagar and her child.
Ishmael's conduct was insulting to Sarah, and she insisted that
he and his mother should be dismissed. This was accordingly
done, although with reluctance on the part of Abraham (Gen.
21:14). They wandered out into the wilderness, where Ishmael,
exhausted with his journey and faint from thirst, seemed about
to die. Hagar "lifted up her voice and wept," and the angel of
the Lord, as before, appeared unto her, and she was comforted
and delivered out of her distresses (Gen. 21:18, 19).

Ishmael afterwards established himself in the wilderness of
Paran, where he married an Egyptian (Gen. 21:20,21).

"Hagar" allegorically represents the Jewish church (Gal.
4:24), in bondage to the ceremonial law; while "Sarah"
represents the Christian church, which is free.
