If there is only bread and onions,
still have a happy face.
“Be content with such things
as you have.”
This made me think about the Jews during the Exodus from Egypt, as well as those who have had to leave their homes during various persecutions throughout the world over time. If one were to substitute “bread” for matzah, it would make just as much sense, if not more:
If there is only matzah and onions, still have a happy face.
“Make the most of what you have when you have it —
(especially during Pesach!)”
