Midrash for I Samuel 3:17

Said R. Juda in the name of Rab: "The curse of a scholar, even if it is without cause, is realized; and this we see to have been the case with Achithophel. When David was digging the Shittin (foundation) of the altar [to reach the watery depth of the earth] the waters of the deep came up and threatened to flood the world; whereupon David said: 'Is there anyone who knows if it is permitted to inscribe the Holy name upon a piece of broken clay and drop it into the water?' No one responded. He exclaimed: 'Whoever amongst ye knows and abstains from answering, shall be choked.' Then Achithophel concluded a fortiori, saying: 'If for the sake of bringing pecae between husband and wife, the Lord has allowed His name [which is written in all sacredness] to be erased by water, so much the more when the peace of the entire world is threatened!' Accordingly, he decided that it is permitted. David then [following this decision] dropped into the water a bit of clay upon which the Holy name was written and the deep came back unto its original place. Nevertheless concerning Achitophel it is written (II Sam. 17, 23) And when Achitophel saw that his council was not followed, etc., and strangled himself." R. Abahu said: "The curse of a scholar, even if it is on condition, is nevertheless realized. Whence do we infer it? From Eli, for Eli said unto Samuel (I Sam. 3, 17) God do so to thee, and more also, if thou hide anything from me. And although Samuel did disclose to him everything, as it is written (Ib.) And Samuel told him all the words, and hid nothing from him, yet it is written [concerning Samuel] (Ib. 8, 3) And his sons walked not in his ways, etc."
