ר‘ יצחק שאול showed much love and patience to all the people he met - men, women and children. He was even kind to animals and birds. This was something his father, ר‘ ניסן , had taught him since he was a young child. His father always told him that we must love everything that ה‘ made, and we must not harm any of His creatures.
ר‘ ניסן had a good reason to teach his son to be merciful, because, when יצחק שאול was a child, like many other children, many times, he had thrown stones at birds, or chased cows, goats, dogs or cats.
ר‘ ניסן had a favorite rooster. Each morning it crowed loudly, waking ר‘ ניסן up at the break of dawn. ר‘ ניסן looked after the rooster himself, making sure it had enough to eat, and keeping it in good health so that it could continue to crow loud and clear. The louder the rooster crowed, the more pleased was ר‘ ניסן . But not so little יצחק שאול . As much as his father loved the rooster, so did his young son hate it. He enjoyed harassing the bird at every opportunity.
One day, unnoticed by יצחק שאול , ר‘ ניסן came into the yard and saw his son behaving cruelly toward all of the farm animals, and the rooster in particular. Suddenly, יצחק שאול felt a heavy hand on his shoulder and looked up to see his father's angry face.
"So, this is the way you spend your time! Treating helpless creatures badly!" his father told him off sternly. "I could never imagine that a child of mine could be so cruel!"
The little frightened boy thought his father would surely give him a beating, he looked so angry. But this was not ר‘ ניסן 's way. He was a teacher of young boys. But in all of his years of teaching, he had never hurt any of his pupils, nor any of his own children. True, his "strap" hung on the wall of the classroom. But if a pupil deserved punishment ר‘ ניסן had only to point to the strap on the wall, and tell him what he deserved, and it was always enough for the culprit.
Entering the house with his son, ר‘ ניסן asked him to bring the גמרא and open it to a specific page. He told him to read the section relating to the מצוה to look after chickens with gentle care. "See how the תורה thinks of everything," ר‘ ניסן enthusiastically explained to his little son. "In another part of the גמרא , we find that we must never sit down to a meal before first looking after our animals.
"So, we see that we must first of all care for ה‘ 's creatures before we look after our own needs. Yet, you, my son, have not only ignored this teaching, but even more, have shown cruelty towards the poor creatures, which I could hardly have believed possible in a child of mine!"
יצחק שאול trembled while his father told him off. He thought his father had finished with him when, instead, he heard his father saying in a very serious voice:
"You know that it is not in my nature to hit anyone, and I have never hit you, but this time, I am going to ask you to take down the strap which is hanging on the wall. I want you to understand the pain you have given to the poor animals that you were so cruel to without thinking."
יצחק שאול took a chair and reached up for the strap which he had never before seen his father use. This in itself showed him how terrible his behaviour had been.
"Before I hit you," ר‘ ניסן said, "I want you to know quite clearly that the only reason I am doing this, is so that you will remember better the pain you have inflicted upon the birds and other living creatures."
These were the first and last blows that יצחק שאול ever received from his father, and he accepted them without a murmur.
ר‘ ניסן quickly went into another room, and a moment later יצחק שאול heard his father crying, deep and painful sobs escaping him which he seemed unable to stop.
When יצחק שאול heard his father sobbing, he realized that it was all his fault for having made his father do something so against his gentle nature. This gave the little boy more pain that the actual hitting, and he decided firmly, from that moment, never again to hurt anything or anyone.
He felt the pain for a couple of days, and walked about full of regret and shame for his bad behavior. On the third day, he suddenly went up to his father, kissed him and asked him, with tears in his eyes, if he would forgive him.
ר‘ ניסן 's eyes also filled with tears as he said to his son tenderly, "My son, you are still a little boy and I, your father, are responsible for your עבירות , which are not quite serious. But it would be dreadful if you grew up to be an unfeeling, cruel person!"
יצחק שאול felt a changed boy. And he never again behaved in a cruel way.
