The verse (Shemot 2:5) states: “Pharaoh’s daughter went down to bathe, to the Nile, and her maidens were walking along the Nile, and she saw the basket in the midst of the marsh, and she sent her maidservant, and she took it.”
On this Rashi comments based on the Talmud (Sota 12b): “They, however, interpreted to mean her hand, [that she stretched out her hand,] and her arm grew many cubits (אַמוֹת) [so that she could reach the basket].”
On this Reb Mendel of Kotzk commented:[1]
“When someone longs for something they should not be put off, that the matter seems impossible. Instead they should stretch out their hand—it’ll surely stretch many cubits.”
A person can do much more than he thinks he can; he should not be dejected when things seem impossible.
