a bundle of sticks-вязанка хвороста
An old man who thought he would not live long called his sons. "Bring me a bundle of sticks,"he said. The young man did so. The father tied the sticks together and gave the bundle to his youngest son. "Can you break the bundle of sticks?" he asked. The boy tried to do so. "No, father. I can't," he said. "Then give the bundle to your brothers. Perhaps one of them can do it." The brothers all tried but with the same result. Then the old man untied the bundle and gave one stick to each son and said; "Can you break one stick?" "Of course," said the young men and each broke his stick.
"You see," said the father, "if you are united and live in friendship, you will be stronger than any enemy. Union is strength."
