Genesis 16:11

“And the angel of the Lord said unto her, etc.] Continued his discourse with her, informing her she should have a son, and what his name should be, and what his character, and the place of his habitation: behold, thou [art] with child; this she knew, and it is said, not for her information, as to this respect, but to lead on to something else he had to acquaint her with, she did not know. Jarchi indeed would have the sense to be, “thou shall conceive” or “be with child”, as was said to Manoah’s wife, (<071305>Judges 13:5); for it is a fancy of his, that Hagar had miscarried, and he, supposes the angel to promise her, that if she would return, or when she should return, she should conceive…”

“Ishmael--Like other Hebrew names, this had a signification, and it is made up of two words--"God hears." The reason is explained.”

“- The Birth of Ishmael 1. הנר hāgār, Hagar, “flight.” Hejrah, the flight of Muhammed. 7. מלאך mal'ak “messenger, angel.” A deputy commissioned to discharge a certain duty for the principal whom he represents. As the most usual task is that of bearing messages, commands, or tidings, he is commonly called a “messenger” ἄγγελος angelos). The word is therefore a term of office, and does not further distinguish the office-bearer than as an intelligent being. Hence, a מלאך mal'ak may be a man deputed by a man Genesis 32:3; Job 1:14, or by God Haggai 1:13; Malachi 3:1, or a superhuman being delegated in this case only by God. The English term “angel” is now especially appropriated to the latter…”

“16:11 Names in Genesis often capture the message of a passage and aid the remembrance of the events and their significance in the history of the faith. The name Ishmael, which means “God hears,” commemorates that the Lord . . . heard Hagar’s cry of distress (see also study note on 16:14-15). This name would have greatly comforted Hagar; God listened to her prayers and acknowledged her complaint.”
