The phrase הרבה ארבה את זרעך (harbah arbeh et zar’ech/zar’echa), “I will greatly increase your offspring” appears twice in the Masoretic text: (i) Sefer Bereshit 16:10, it refers to the seed of Hagar, the wife of Abraham (ii) Sefer Bereshit 22:17, it refers to the seed of Abraham, the husband of Hagar.
Similarly, the gematria of this phrase is equal, 1.118. This phrase consists of four Hebrew words: הרבה (harbah) 212; ארבה (arbeh) 208; את (et) 401 and זרעך (zar’ech/zar’echa) 297. Amazingly, the gematria of the promise ארבה (arbeh), “I will increase” in both verses is equal to that of הגר (Hagar), 208. Similarly, the phrase אב המון (av hamon), lit. “father of a multitude” which the phrase refers to Abraham, in fact, this appears twice in the Tanach (Sefer Bereshit 17:4-5), and the gematria of this phrase אב המון (av hamon) is also 208, the same as that of הגר (Hagar), 208.
Meanwhile, the promise of the LORD about Ishmael, it also appears twice in the Tanach: (i) the promise of God to Hagar, and there are two words to express the promise: הרבה (harbah) and פרא (pere) in the Sefer Bereshit 16:10-12, (ii) the promise of God to Abraham, and there are also two words to express the promise: הפריתי (hifreiti) and הרביתי (hirbeiti) in the Sefer Bereshit 17:20.
The Hebrew words הרבה (harbah) and הרביתי (hirbeiti) or רבו (rebu) have the same root, and the root of the verbs is רבה (rabah). Similarly, the Hebrew words פרא (pere) and הפריתי (hifreiti) or פרו (peru) have the same root, and the root of the words is פרה (parah). Based on the Sefer Bereshit 1:22 Rashi explains the word פרו (peru), lit. “be fruitful” as being of the same root as פרי (peri), “a fruit.” Thus, פרו (peru) means “bring forth fruit”, and the root of the verb פרו (peru) is פרה (parah) .
Interestingly, the Hebrew word רבה (rabah) is used to state “shall multiply” for man and all animals, but the Hebrew word פרה (parah) is only used to state “shall be fruitful” for man and the fish per se, not all animals, or even to the wilderness animals. Regarding the fish and man, the verse uses a double expression of increase, פרו ורבו (peru u-rebu), “be fruitful and multiply, whereas regarding the fowl only one expression, ירב, “it shall multiply”, is used. Regarding the birds, the Torah does not state “shall be fruitful and multiply, for that expression is only applicable to man and to fish whose sustenance is easily accessible and they are therefore free to be fruitful and multiply. But as for birds and also animals and beasts, by contrast, sustenance is not that easily accessible to them, and hence they are not as free to reproduce .
Ishmael is a man, not an animal, so that why the text uses the root of the word פרא (pere), derived from the verb פרה (parah). Obviously, the Hebrew linguists know that the verb פרה (parah) is only applied to a man, not to the desert animals. Rabbi Yaakov Tzevi Mecklenburg also confirms that both terms פרא (pere) and יפריא (yafriya) are derived from the same root. Therefore Hagar really knew this as a good prediction of God in the future. It indicates that the phrase פרא אדם (pere adam) in the Sefer Bereshit 16:12 is really to mean as a positive atribute, not as a negative one. It is a good news, not as a bad news for Hagar; because Ishmael will be a fruitful man (fertile of man), not as the wild-ass of man.
Amazingly, the phrase ויקראת שמו (ve yeqarat shemo), lit. “and you shall call his name” appears twice in the Tanach: (i) ויקראת שמו ישמעאל (ve yeqarat shemo Yishma’el), “and you shall call his name Ishmael” (Genesis 16:11); (ii) ויקראת שמו עמנואל (ve yeqarat shemo ‘Immanu’el), “and you shall call his name Immanuel” (Isaiah 7:14). This teaches us that both are the heavenly names from God, and both are God’s salvation in the light of heaven. Obviously, Ishmael and Immanuel are good men, and only for Ishmael and Immanuel, the phrase appears twice in the Tanach.
Rabbi Yaakov Tzevi Meclenburg said:
“the Hebrew phrase פרא אדם (pere adam), most commentators view this as an unpleasant prediction for Hagar, understanding it as a prediction that Ishmael would be violent and corrupt. I believe they are wrong! How could the angel foretell this part of the future to Hagar? We do not find these kinds of predictions anywhere! Moreover, how would this inspire her to return to the home of Abram? The angel meant to tell her something to make her change her mind about returning ….. We have a similar meaning of that word in Hosea 13:15, בין אחים יפריא, “he will flourish between reeds” etc. The word describes “bearing fruit.” I have found a similar explanation in the Zohar page 192 on Parshat Balak. In other words, the angel informed Hagar that her son would be fruitful and would multiply just as the LORD foretold Abraham in Sefer Bereshit 17:20, “I have blessed him and I have made him fruitful, and I will increase him very much and make him into a great nation. All of this include in the term פרא אדם (pere adam)”
Amazingly, the Samaritan text of the Torah, Sefer Bereshit 16:12 also confirms the phrase פרה אדם (para adam), lit. “fruitful man”, and the term פרה at the verse is really derived from the verb פרה (parah). Sefer Bereshit 16:12
והוא יהיה פרה אדם ידו בכל ויד כל בו ועל פני כל אחיו ישכן
“Ve hu yihyeh parah adam yado be kol ve yad kol bo ve ‘al phenai kol achaiv yishkon“
“He will be fertile of man. His hand will be with everyone. And everyone’s hand will be with him. And he will live among all his brothers” 
Ishmael will be פרה אדם (para adam), lit. “a fruitful man.” And the gematria of his name is 451. Gematria is numerical value in Hebrew Torah. Every Hebrew letter has a numerical equivalent called it גימטריא (gematria). Interestingly, the gematria of the Hebrew name ישמעאל (Yishmael) is in fact 451; it is equal to that of both Hebrew names אברם (Abram), 243 dan הגר (Hagar) 208. Obviously, the gematria of ישמעאל (Yishmael) is 451, the same as that of אברם והגר (Abram ve Hagar), 451. Abraham is the father of Ishmael, Hagar is the mother of Ishmael. Hagar bore Ishmael for Abraham.
Moreover, the gematria of ישמעאל (Yishmael) has a numerical equivalent with the gematria of הגר (Hagar). The gematria of ישמעאל (Yishmael) is 451, and the gematria of הגר (Hagar) is 208. What does it mean in the light of numerical value? The numerical value of Yishmael is 451 (4 + 5 + 1 = 10); it is the same as that of the numerical value of Hagar, 208 ( 2 + 0 + 8 = 10). Interestingly, the numerical value of אברם (Abram) is 243 (2 + 4 + 3 = 9). What does it mean as the promise of God in the future? The numerical value of Abram (9), Hagar (10) and Yishmael (10) is totally 29, and this teaches us about the gematria of their offspring, במאד מאד (be-meod meod), 92, it is the same as that of the gematria of מחמד (Muhammad), 92. So, the numerical value of Abram, Hagar and Yishmael is totally 29, and this can be rearranged to the gematria of their offspring, 92. Also, the word בהבראם (behibar’am), lit. “when they were created” in the Sefer Bereshit 2:4 has the same episteme. The letters of this word בהבראם can be rearranged to spell באברהם (be Abraham), “with Abraham”, for it was in Abraham’s merit that the heavens and the earth were created (Bereshit Rabbah 12:9) .
Meanwhile, the Hebrew name הגר (Hagar), the wife of Abraham appears 12 times in the Torah; and Ishmael bore 12 sons, see Sefer Bereshit 25:13-16. Amazingly, the Arabic name Isma’il also appears 12 times in the Quran. It means that the Quran also confirms the gematria of Ishmael. Indeed, the Torah has a link with the Quran.
