[ALFENUS libro septimo digestorum. ] §19.2.29.prIn lege locationis scriptum erat: 'redemptor siluam ne caedito neue cingito neue deurito neue quem cingere caedere urere sinito'. quaerebatur, utrum redemptor, si quem quid earum rerum facere uidisset, prohibere deberet an etiam ita siluam custodire, ne quis id facere possit.
[ALFENUS, Digest, book 7] In the terms of the lease, it was written: 'The contractor shall not cut down the forest, nor girdle the trees, nor burn them down, nor allow anyone to girdle, cut down, or burn them.' The question was asked whether the contractor, if he had seen anyone doing any of those things, was only obliged to prevent them, or whether he was also obliged to guard the forest in such a way that no one could do so.
respondi uerbum sinere utramque habere significationem, sed locatorem potius id uideri uoluisse, ut redemptor non solum, si quem casu uidisset siluam caedere, prohiberet, sed uti curaret et daret operam, ne quis caederet.
I replied that the word 'to allow' has both meanings, but it seems that the landlord rather intended that the contractor should not only prevent someone if he had by chance seen him cutting down the forest, but also take care and make every effort that no one should cut it down.
