The Talmud

“The burden is equal to the horse's strength.”

“Three things are good in little measure and evil in large: yeast, salt and hesitation.”

“The deeper the sorrow the less tongue it hath.”

“Everyone whose deeds are more than his wisdom, his wisdom endures. And everyone whose wisdom is more than his deeds, his wisdom does not endure.”

“It is not upon thee to finish the work; neither art thou free to abstain from it.”
