This Shabbat, Shabbat before Tisha B'Av is called vision (Shabbat chazon) Shabbat, in the name of the Haftarah (prophets chap.) we are reading: "the prophecy of Yeshayaho son of Amozh…" also from the language of vision (in Hebrew – Chazon), any Jew shows this Shabbath (his soul) of the temple to awaken the longing for redemption.
The chapter "Dvarim" is always read on the Sabbath before Tisha B'Av, "Shabbath Vision." There are many clues in the chapter relating to Tisha B'Av. One of them is mention of Spies sin, reproof of Moses to the people of Israel, for the night where the children of Israel cried because the words of the spies was Tisha B'Av, made for that day of weeping for generations.
When Moses mentions the sin of the spies he says: "You complained in your tents and say, G-d hates us and drove us out of Egypt."
Moses says something here that does not appear in the description of Spies sin in Chumash Bamidbar (the fourth part of the books of the Pentateuch). There is told that the people of Israel cried and complained G-d brings us to this land to fall by the sword. The claimed was that lack of faith in the ability of G-d. But here Moses adds, that the children of Israel argued the G-d alleged hate them.
Moses says further: "You complained to your tents." I mean, in addition to the overt claims, detailed in Chumash Bamidbar, the children of Israel gathered in tents and speak ill of the G-d. What were the words of their evil? Rashi brings the name of study, they complained about the fact that G-d took them out of Egypt, that land of the drinking water from the Nile, and he brings them to Israel who needs the mercy of the rains.
Both: the claim that G-d hates Israel and Egypt is better country from Israel, are obviously false claims. Well known that G-d loves Israel, proof of G-d's love of Israel made them the great miracles in Egypt, Red Sea and the desert.
Also of course the blessing of rains better ten times from the blessing of the Nile. The Nile water must be brought to the fields, and if it is a high field from the sea level, has to raise them there by buckets.
Therefore, these claims do not spread out in the Chumash Bamidbar, for false claims of the children of Israel could not argue openly. Here Moses discovers the things that were said in secret - "You complained in your tents." There, in the tents, the people of Israel grumbled libel and talk about G-d and the Land of Israel.
But the truth is, of course, G-d loves the people of Israel even when they're grumbling and angry against him. Highlighted precisely this love on the Saturday before Tisha B'Av, in order to strengthen and comfort the people of Israel these days, and hope for completed the real redemption.
