[IDEM libro quadragensimo secundo ad Sabinum. ] §2.14.50.prNon impossibile puto in contractibus depositi, commodati et locati et ceteris similibus hoc pactum: 'ne facias furem uel fugitiuum seruum meum', hoc est: ne sollicites ut fur fiat, ut fugitiuus fiat: ne ita neglegas seruum, ut fur efficiatur. sicut enim serui corrupti actio locum habet, ita potest etiam haec pactio locum habere, quae ad non corrumpendos seruos pertinet.
[THE SAME, On Sabinus, book 42] I do not think that in contracts of deposit, loan for use, lease, and other similar ones, the following agreement is impossible: "Do not make my slave a thief or a runaway," that is: "Do not entice him to become a thief or to become a runaway," or "Do not neglect the slave in such a way that he becomes a thief." For just as the action for corrupting a slave lies, so also can this agreement lie, which pertains to not corrupting slaves.
