If you should say in your heart: These nations are more numerous than I; how can I dispossess them? You shall not be afraid of them (7:17–18)
When you understand that the nations are more numerous than you, and that you, with your own power, cannot defeat them, but are totally dependent on G‑d's help, then you need not fear them. But if you begin to believe that you can defeat them on your own, then you indeed have great cause for fear.
(Maasei Hashem)

I beseeched G‑d at that time (Deuteronomy 3:23)
Prayer is called by ten names: cry, howl, groan, song, encounter, stricture, prostration, judgment and beseeching.
[These synonyms for prayer are derived from: Exodus 2:23–24, Jeremiah 7:16, Psalms 18:6, Deuteronomy 9:25, Psalms 106:30 and Deuteronomy 3:23.]
(Midrash Rabbah)
Prayer is called by [thirteen] names: cry, howl, groan, stricture, song, prostration, encounter, judgment, entreaty, standing, appeal and beseeching.

(Sifri)
The fast of Tishah B'Av begins this evening at sunset.
Some of the fast's mourning practices--such as refraining from Torah study other than texts related to the events and nature of the fast day--are observed beginning from midday today.
Finish eating by sunset. After nightfall say, "Blessed is He who distinguishes between the holy and the mundane." No Havdalah tonight, but light a candle and recite the fire blessing. Havdalah is recited after the fast (omitting the candle and incense blessings).
"Eichah"--the Book of Lamentations--is read tonight in the synagogue after evening prayers.
See "Laws and Customs" for tomorrow, Av 9, for the particular obervances of the fast day.

These are the words which Moses spoke to all Israel on the other side of the Jordan, in the desert, in the Aravah, opposite Suf, between Paran and Tofel, and Lavan, and Chatzerot, and Di-Zahav (Deuteronomy 1:1)
According to the Sifri, the numerous place names listed here are not landmarks indicating where Moses spoke these words—indeed, some of these places do not even exist as geographical locations. Rather, these are words of rebuke by Moses to the people of Israel. Instead of mentioning their sins outright, he alluded to them with these place names:
"In the desert"—the time they complained: "If only we would have died in the desert" (Exodus 17:3).
"In the Aravah (Plain)"—their worship of Baal Peor in the Plains of Moab (Numbers 25).
"Opposite Suf"—the trouble they made at the shores of Yam Suf, the Red Sea (see Exodus 14:11 and Rashi on Exodus 15:22).
"Paran"—the sin of the spies, who were dispatched from Paran (as recounted in Numbers 13 and later in our own Parshah).
"Tofel" and "Lavan" (meaning "libel" and "white")—their libeling the white manna (Numbers 21:5).
"Chatzerot"—where Korach's mutiny against Moses took place.
"Di-Zahav" (literally, "too much gold")—the sin of the golden calf.
(Sifri, Rashi, et al)
