창세기 16:11 해설: Rashi, Ramban, Kitzur Ba'al HaTurim & Radak

הנך הרה BEHOLD THOU WILT BE WITH CHILD — when you return you will conceive, just as the same phrase הנך הרה (Judges 13:7) spoken of the wife of Manoah (where it certainly appears to be thou wilt conceive in the future).

AND THOU SHALT CALL HIS NAME ISHMAEL. The angel informed Hagar that his name will be Ishmael — just as in the verse, Behold, a son shall be born unto the house of David Josiah by name³⁶⁰I Kings 13:2. — and he told her that she should so call him, and thus remember that G-d heard her affliction.³⁶¹The name Ishmael (G-d heareth) is, as the angel explained to Hagar, “because the Eternal hath heard thy affliction.” (Verse 11.) Now Abraham either called him by this name on his own,³⁶²Verse 15: And Abraham called the name of his son, whom Hagar bore, Ishmael. with the intent that G-d hear him and answer him, or the Holy Spirit rested upon him, as Rashi has it, and he called him Ishmael because G-d had heard his mother’s affliction, as the angel had said.
The correct interpretation appears to me to be that the angel commanded Hagar that she call him so, but she, being a concubine,³⁶³Verse 3 above is no proof to the contrary, as it may express only Sarai’s desire. was afraid to give a name to her master’s son, so she revealed the matter to him, and Abram fulfilled the word of G-d. Scripture, however, did not need to delve at length into this matter.

"And you shall call" 4 places In the Tanakh it said, "And you shall call," and elsewhere it says, "And you shall call evil upon you" (Jeremiah 2:19). "And you shall call His name Immanuel" (Isaiah 7:14). "And you shall call for salvation on your walls" (Isaiah 62:6). Through Ishmael's name, "And you shall call evil upon you," but through the calling of Immanuel, "you shall call for salvation."

וְיֹלַדְתְּ בן AND THOU SHALT BEAR A SON — The word appears to be grammatically a combination of the perfect tense וְיָלַדְתְּ and the participle וְיֹלֶדֶת but it is similar in sense to וְיֹלֶדֶת (the participle); so, also, (Jeremiah 22:23) “O thou that dwellest יֹשַׁבְתְּ) in Lebanon, and art nestled (מְקֻנַּנְתְּ) in the cedars.”
