Talmud su Proverbi 16:6

It is written (Prov. 16:6): “When the Eternal likes the conduct of a person, even his enemy will make peace with him.” Rebbi Meïr says, that is the dog. Rebbi Joshua ben Levi says, that is the snake. The shepherds milked; there came a snake, ate from it, but the dog observed it. When they came to eat, he started barking at them but they did not pay attention. At the end, he ate and died. A person made ground garlic in his house. There came a mountain snake and ate from it but the house snake observed it. When the people from the house came to eat from it, it [the house snake] started to throw dust down on them¹⁷⁹Another version of the same story is in Gen. rabba 54(1). In that source, all authors are late Amoraïm; the snake is identified as the enemy by R. Samuel.. When they did not pay attention, it threw itself on it. A person invited a rabbi and let the dog sit next to him [the rabbi]. He said, how did I merit this insult? He said, rabbi, I am repaying his [the dog’s] good deed. Kidknappers came to town. One of them came and wanted to take my wife but he [the dog] ate his testicles.
