Hagar (hâ'gar), flight. An Egyptian woman, the bond-servant of Sarah, whom the latter gave as a concubine to Abraham, and Hagar despised her mistress. Genesis 16:1-4. Hagar fled. On her return she gave birth to Ishmael, and Abraham was then 86 years old. When Ishmael was about 16 years old, he was caught by Sarah making sport of her young son Isaac, and Sarah demanded the expulsion of Hagar and her son. Hagar again fled toward Egypt, and when in despair at the want of water, an angel again appeared to her, pointed out a fountain close by, and renewed the former promises to her. Genesis 21:9-21. Paul, Galatians 4:25, refers to her as the type of the old covenant.
