A Shepherd raised a Wolf to steal from neighbors. The Wolf was grateful but warned the Shepherd to be even more cautious now.
False men cannot be trusted.
A Shepherd found a Wolf’s cub and raised it; teaching it to steal lambs from neighboring flocks. The Wolf warned the Shepherd: “Since you have taught me to steal, you must keep a sharp eye out or you will find your flock diminished.”

Townsend version
A Shepherd once found the whelp of a Wolf and brought it up, and after a while taught it to steal lambs from the neighboring flocks. The Wolf, having shown himself an apt pupil, said to the Shepherd, “Since you have taught me to steal, you must keep a sharp lookout, or you will lose some of your own flock.”

Lupus Parvulus et Pastor
Pastor, lupum parvulum cum invenisset, eum penes se enutrivit ac, ubi adolevit, pecudes ex vicinis armentis rapere docuit. Quod lupus cum egregie didicisset, “Cave,” olim pastori ait, “ne me rapiendi artem postquam docueris, multas ex tuis gregibus oves desideres.”
