You shall surely give him, and your heart shall not be grieved when you give to him, because for this thing Hashem your God will bless you in all your work and in all that you put your hand to.
English: "You shall surely give" — I know only a large gift; from where do I know a small gift? From the doubled language "give, you shall give"—in every case.
On the daf / in context: Even a poor person who lives on charity is obligated to give a small amount to others.
Type of Learning
Derash on the verse (Bava Metzia) — even a small gift fulfills the mitzvah.
What Is Learned
The obligation to give includes even a minimal gift; a poor person who receives charity must himself give something.
