> The baculum (also penis bone, penile bone, or os penis, os genitale or os priapi) is a bone found in the penis of many placental mammals. It is absent in the human penis, but present in the penises of other primates, such as the gorilla and chimpanzee.
Well, ancient Israelis were quite likely to have known that sheep and goats have a baculum (and perhaps wonder why they do not), and less likely to have known about gorillas and chimpanzees.
