One Hundred
שמות ו,ו: לָכֵן אֱמֹר לִבְנֵי־יִשְ רָאֵל
The Baal HaTurim notes that the Gematria of the word לכן equals 100 of the Avos (each who had a concept of 100) which was the source of the merit that the nation was redeemed from Mitzrayim.
Avrohom has his son Yitzchak when he was 100 years old. Yitzchak had field that yielded one times its expected crops. And Yaacov fathered all his children by the age of 100.
Yaacov was 63 years old when he left Beer-sheva. He learned for 14 years in the Yeshivah of Ever. He then worked for Lavan for 20 years and was two years on the road. There his last child, Binyamin was born.
Aharon’s Staff
שמות ז ,יב: וַיַשְלִיכוּ אִיש מַטֵהוּ וַיִהְיוּ לְתַנִינִם וַיִבְלַע מַטֵה־אַהֲרֹן אֶת־מַטֹתָם:
The Baal HaTurim comments that the word מאתם appears again in the episode of Korach (17:21) "and Aharon's staff among their staffs (besoch Matosom)". He cites a Medrash which relates that there, just like here, Aharon's staff swallowed the staffs of all the other tribes while it was in the Ohel Moed, and that this was the reason that they did not blossom. And it was when they retrieved Aharon's staff from the Ohel Moed that it spat them out. That is why, when the Torah writes "and Moshe took out all the sticks (kol hamatos), the word "haMatos" is written without a 'Vav', since it was really only Aharon's staff that he retrieved. This is why their staves were unable to blossom.
The Frog
שמות ד ,ב : וּבְכָה וּבְעַמְךָ וּבְכָל־עֲבָדֶיךָ יַעֲלוּ הַצְפַרְ דְ עִים:
The Baal haTurim observes the word ובכה appears two other times in Tanach besides this time. Another time it appears in Dovid’s song of deliverance (Shmuel II 22,30) כי בכה ארוץ גדוד (for with You I will run towards a troop. The third time is in Tehillim 141,8 בכה חסיתי (I have sought refuge in You).
This teaches that the frogs swarmed through Mitzrayim in waves of troops. Further, the plague of the frogs did not affect the Jews since they sought refuge in HaShem.
Throughout this plague, the Torah uses the term צפרדעים which is plural, a total of 10 times. However, at the onset of the plague, the word used is צפרדע in singular. This implies that initially only one frog emerged from the river, and then the Egyptians struck it and swarms of frogs streamed forth from that first frog. According to another opinion, the first frog emerged from the river and crocked very loudly to summon all the frogs of the world. These frogs swarmed into Mitzrayim from all directions.
Prayers of the Righteous and Rain
שמות ט ,לג : וַיַחְדְלוּ הַקֹלוֹת וְהַבָרָד וּמָטָר לֹא־נִתַךְ אָרְ צָה:
The Baal haTurim observes that the word נתך occurs three times in Tanach: (1) here where the rain did not reach the ground; (2) Shmuel 21,10 regarding the executed sons of Shaul that remained hanging until the rain came down; and (3) Yirmiyahu 42, 18, “Just as My anger and My wrath were poured down upon the people of Yerushalyaim.”
This indicates that the prayers of the righteous can withhold the rain. The rain stopped in mid-air in response to the prayer of Moshe. Also, the righteous can cause the rain to fall as did Dovid’s prayers (After a famine of three years, HaShem told Dovid it was due to the house of blood of Shaul who had killed the Givonim. Dovid had handed over seven of Shaul’s descendants to be hanged by the Givonim to avenge the death of seven Giveonim that had be killed in that incident. The bodies remained until they received a heavenly sign of forgiveness to the Jews in the form of rain as a result of prayers of Dovid.) Similarly HaShem will atone for Yerushalayim in response to the prayers of the righteous.
