The Torah Portion of Bamidbar:
The Chumash of Bamidbar is also called the Chumash of Counting (i.e. similar to the idea of calling it the Book of Numbers in English) because within it is written the number of all of the children of Israel.
"Their counted ones for the tribe of Dan: 62,700." (Bamidbar 1:39)
The Chafetz Chaim says that when we read in the Torah Portion of Vayigash "the sons of Dan, Chushim", we pity him because he had only one son, but in the Torah Portion of Bamidbar we see that the tribe of Dan had the largest number after the tribe of Yehudah, and from this we see the great importance of one soul in Israel.
"Their counted ones for the tribe of Dan: 62,700." (Bamidbar 1:39)
It is said that Dan would always request from his father to pray for him, and Binyamin, who had 10 sons, did not request that he pray for him. After the event of the Pilegesh B'givah there remained in the tribe of Binyamin only 600 people, and from this we see that a person always needs to pray.
"As they camped so they traveled". (Bamidbar 2:17)
The Ramchal says, there are people who when they are in their homes act strictly with all the Jewish laws and when they go outside on a journey they take matters lightly. And the opposite case is also true, there are people that when they are at home, take matters lightly, but outside of their houses they act strictly in front of the eyes of the public to show others that they are righteous. Therefore the verse says, "as they camped so they traveled", that one should behave with the same behavior whether at home or outside.
Haftora: "And the number of the children of Israel will be like the sands at the sea". (Hoshea 2:1)
Chag HaShavuot:
"Moshe received the Torah from Sinai". (Avot 1:1)
Megillat Ruth:
The Torah Portion of Bamidbar has 159 verses. Haftora: "V'haya mispar yisrael" (Hoshea 2)
Chag HaShavuot: Two Torah Scrolls are taken out. In the first, 5 men are called for reading in the Torah Portion of Yitro, "Bachodesh hashlishi". In the second, the Maftir is read from the Torah Portion of Pinchas, "Uvayom habikurim". Haftora: "Vayehi beshloshim shana" (Yechezkel 1) until "Kol midabair", then skipping to Chapter 12 verse 3.
