No one shall put anything before his sons or his cattle by measure or weight. But if he fetches something with a sea or with a terkab, he may serve it to his cattle; he fetches it with one ladle, he may put it before his sons; only he should not pay attention to it For this they have from R. Elazar b. R. Zadok and Abba Shaul b. Botnit said that they had been traders in Jerusalem all their lives and that on the eve of a holiday they filled their measurements and gave them to the buyers on the holiday because of disruption of the house of study; but the other sages say: Even on a working day they did so because of the complete emptying of the Dimensions. He also collected jars of oil and his colleague pitchers wine because of the complete emptying of the measure, and they brought it up to the treasurers. They said to them: You are not obliged to do this. They said to them: We don't want them. They said to them: Since you have made the law stricter for yourselves, they belong to the public; the needs of the public should be satisfied with it!
