Today, if you listen to His voice, Rabbi Levi said, if the Israelites would observe even one Shabbat according to its laws, they would immediately be redeemed, as it says, "Today, if you listen to His voice." And it is written, "Guard the Sabbath day to sanctify it." Do not harden your hearts as at Meribah. Israel tested the Lord ten times, as it says, "They tried Me these ten times."
Twice at the sea, and they rebelled against the sea. At the Sea of Reeds, in the midst of the sea. Twice in the wilderness, and once with the manna, and once with the golden calf. Once at Paran, and once with the spies, which was the most difficult of them all.
Abraham our father also tested the Lord ten times, which were: once in Ur Kasdim, and when he left his land, and during the famine, and twice with Sarah, in Pharaoh's and Abimelech's houses, and the circumcision, and between the two pigeons, and with Isaac, and with Ishmael. Our fathers tested the Lord ten times in the wilderness, as it says, "In the wilderness, in the Arabah." But they were only seven.
Where are the other three? They were at Taberah, Massah, and the Graves of Lust. And why did they not rely on the first seven, which were harder than the last three?
