As a kid I would cry at the drop of the hat, my mom would tell me that if I continued to cry she would give me something real to cry about. My Mom however, wasn’t the first to use that phrase, it was God who invented it, he invented it on the 9th of Av and it’s all explained in the Book of Numbers.
In the book of Numbers (beginning with chapter 13) Moses sends twelve spies into Canaan, ten of them came back with a report that the land was unconquerable because it was inhabited with strong giants. This report caused cries throughout the Israelite settlement, they begged Moses to take them back to Egypt.
Now realize this happened only four months after they left Egypt when they witnessed all those miracles (the ten plagues that gave them freedom and the splitting of the Reed Sea), It was only two months since the revelation at Sinai when they heard God’s voice and received the Ten Commandments. And don’t forget they were being led by a column of fire and being fed by food from heaven (manna, which BTW translates into English as “what’s this?”). But even with all of those miracles those newly freed slaves lost their faith in God and his promise to help them conquer the land. Because of the report they were afraid and wanted to go back to Egypt and bondage.
God’s response was not only that the generation that knew slavery would die out in the desert, but also that the 9th of Av (Tisha b’Av) will be a horrible day for the Jews until the coming of the Messiah. In other words, just like my mom used to say, God gave the Jews something to cry about.
From that day forward, horrible things happened to the Jewish people on or around Tisha b’Av…
