The pinnacle: giving in a way that makes future tzedakah unnecessary. A partnership, a loan, a job — the highest form of giving roots the recipient in dignity.
The Summit
The Rambam's highest levels — one and two — represent a qualitative shift from all the levels below. Levels three through eight all describe acts of direct giving: money or resources transferred from a person who has to a person who needs. The top two levels describe something fundamentally different.
Level two: "Giving a gift or loan or entering a business partnership or finding employment for a poor person before they become impoverished."
Level one is a specialization of level two — doing all of this for a relative, where the obligation and intimacy are greatest.
