Midrash sobre Proverbios 11:13

(Fol. 31) Our Rabbis were taught: "Whence do we know that one of the judges, when leaving court, must not say: 'I was in favor of the defendant, but my colleagues were against me, and I could not help it, for they were in the majority?' The passage, therefore reads (Lev. 19, 16) Thou shalt not go up and down as a tale-bearer among thy people. And another passage says (Prov. 11, 13) He that walketh about as a tale-bearer revealeth secrets." There was a disciple concerning whom there was a rumor that after twenty-two years he disclosed a secret thing which was taught in the college. R. Ami drove him out of the college, and announced: "This man is a revealer of secrets."

7) And whence is it derived that if one of the judges goes out, he should not say "I found for you, but what can I do, my fellow (judges) are in the majority"? From "You shall not go rachil among your people." And (Mishlei 11:13) "He who goes rachil reveals a secret, and the faithful of spirit conceals a thing."

This may be compared to a slave to whom a king entrusted all his possessions. When the slave was about to die, he summoned his sons to tell them where the will and writ of manumission were to be found so that they could become free men. The king discovered this and remained at his bedside. When he saw the king, he set aside the thing he wished to reveal to them, and admonished them instead, saying: “You are the king’s slaves, honor him as I have all my life.” Similarly when Jacob summoned his sons to reveal to them what would transpire in the Messianic age, the Holy One, blessed be He, appeared before him and said: You have summoned your sons, but you did not summon Me. And thus Isaiah said: Yet thou hast not called me, O Jacob; neither hast thou wearied thyself about Me, O Israel (Isa. 43:22). When Jacob saw Him, he began to tell his sons: I implore you to honor the Holy One, blessed be He, just as my ancestors honored Him, as is said: The God before whom my fathers Abraham and Isaac did walk (Gen. 48:50). They replied: We know what is in thy heart, and they declared together: Hear, O Israel, the Lord our God, the Lord is One (Deut. 6:4). Upon hearing this, Israel bowed down upon the bed’s head (Gen. 47:31), and began to say in a whisper: Blessed be the name of His glorious kingdom for ever and ever. The Holy One, blessed be He, said: It is the glory of God to conceal a thing; but the glory of kings is to search out the matter (Prov. 25:2). Apparently you do not possess this attribute, For he that goeth about as a talebearer revealeth secrets; but he that is of a faithful spirit concealeth a matter (Prov. 11:13).
