Hillel the Elder

Hillel the Elder when his students would leave

He went with them

His students said to him:

Rabbi, where are you going?

He said to them:

To give charity to a guest who is in my home.

They said to him: Every day you have a guest:

And he said to them: Because it is a sad soul who does not host with his body:

Today it is here, tomorrow it is not here.
