«قَرْقَرْ جُرْنَكْ وَلَا تْقَرْقَرْ مَخْزَنَكْ»

This is advice about where thoroughness pays and where restraint does. Qarqar here means clearing something down to its bottom, and jurn is the threshing floor. Grain left in the open is at the mercy of passersby, so any scrap there is forfeited; grain behind a storeroom door keeps its worth, and a held-back portion hedges against lean days.

A folk belief runs alongside the practical advice. Bare shelves were believed to court bad luck, and the same instinct reached the purse, where a lone coin left inside was thought to summon more money. This is superstition rather than economic reasoning, but it explains why households avoided draining any reserve completely.

Draw on it when one resource lies exposed to loss and another sits secure: urge complete collection of the vulnerable portion, while insisting that some of the protected portion be held in reserve rather than drawn down to nothing.
