Answer:
Charity.
Explanation:
By definition Charity is giving to people that are typically in need. In this case, note the quotes:
"So when you give to the needy..." (emphasis added).
The next part is the explanation of how to give to the needy.
Do not: "... announce it with trumpets.... Truly I tell you, they have recieved their reward in full."
Instead: "Give to the needy... not let your left hand know what your right hand is doing... then your Father... will reward you."
