«كِبِيرِ الْقُومْ خَادِمْهُمْ»

The saying claims that a group's true leader shows that rank by looking after its members. Here the 'great one' means the head or chief, not someone large or merely older. Authority is measured by care, effort, and attention to others' needs, not by privilege.

It can praise a senior figure who works hard for the group, or it can quietly correct someone who treats status as permission to be served instead of a duty to serve.

Say it when praising a senior person who takes on humble work for others, or to remind someone in charge that position brings duties. Said directly to a person in authority, it can sound like a pointed reminder rather than simple praise.
