An oak and a reed were arguing about their strength. When a strong wind came up, the reed avoided being uprooted by bending and leaning with the gusts of wind. But the oak stood firm and was torn up by the roots.
AesopA farmer who had a quarrelsome family called his sons and told them to lay a bunch of sticks before him. Then, after laying the sticks parallel to one another and binding them, he challenged his sons, one after one, to pick up the bundle and break it. They all tried, but in vain. Then, untying the bundle, he gave them the sticks to break one by one. This they did with the greatest ease. Then said the father, "Thus, my sons, as long as you remain united, you are a match for anything, but differ and separate, and you are undone".
