Talmud zu Tehillim 22:21

“The place of stoning was two man-sizes high,” etc. It happened that a pious man was walking on the road when he saw two people having sex with a bitch. They said, we know that this is a pious man, he will go, testify against us, and our lord David will kill us⁷⁵Which the king by his police powers could do on the information of one witness.. Therefore, we shall be quicker than him and testify against him. They testified against him and he was sentenced to be executed. That is what David said⁷⁶Ps. 22:21., Rescue my soul from the sword, From the dog my only one! From the sword, Uriah’s sword. From the dog, the pious man’s dog.
