ביטוי (אנגלית)

Empty trees (barren trees) make the most noise

הגדרה (אנגלית)

Barren trees make noise with their branches moving in the wind. Figuratively: Those who are empty of knowledge are often the ones who make their voices heard and stand out among the public. See also: 'A coin in a pitcher makes a rattling sound.'

("They said to the barren trees: Why is your voice heard? They replied: If only we could make our voices heard and be seen... Rav Huna said: But barren trees, because they are light in their fruit, their sound is heard" - Genesis Rabbah 16:3)
