Talmud su Salmi 116:6

Rebbi Yannai feared it so much that he put his bed on four beams [standing] in water. Once he stretched out his hand and found it near himself. He said, take it away from me, (Ps. 116:6) “the Eternal watches over the simple-minded.”

It was stated: Rebbi Eliezer said, one may eat figs and grapes in the night without worry, since it is said (Ps. 116:6) “the Eternal watches over the simple-minded.” Rebbi Jonah in the name of Rav: A fish with pecking marks is forbidden. Rebbi Ḥizqiah, Rebbi Tabi in the name of Rav: A living fish with pecking marks is forbidden. If it is salted, through the salt it trembles¹⁷⁶It is visible whether the salted fish is infected or not.. Dead¹⁷⁷If it is clear that some animal pecked at the fish after it died., one cuts out the place of the pecking.
