[PAULUS libro secundo quaestionum. ] §45.1.125.prCum stipulamur 'quidquid te dare facere oportet', nihil aliud in stipulationem deducitur quam quod praesenti die debetur: hoc enim solum haec stipulatio demonstrat.
[PAULUS, Questions, book 2.] When we stipulate "whatever you ought to give or do," nothing other is brought into the stipulation than what is due on the present day; for this alone is what this stipulation points to.
