Adam Clarke on Genesis 16:11

And shalt call his name Ishmael - ישמאעל Yishmael, from שמע shama, he heard, and אל El, God; for, says the Angel, The Lord Hath Heard thy affliction. Thus the name of the child must ever keep the mother in remembrance of God's merciful interposition in her behalf, and remind the child and the man that he was an object of God's gracious and providential goodness. Afflictions and distresses have a voice in the ears of God, even when prayer is restrained; but how much more powerfully do they speak when endured in meekness of spirit, with confidence in and supplication to the Lord!
