Hæc igitur dicit Dominus: In hoc scies quod sim Dominus: ecce percutiam virga, quæ in manu mea est, aquam fluminis, et vertetur in sanguinem.
Thus therefore saith the Lord: In this thou shalt know that I am the Lord: behold I will strike with the rod, that is in my hand, the water of the river, and it shall be turned into blood.
Domino ergo dic hoc: in hoc sci quod es Domino: ecce percute virga, que in manu meo es, aqua de flumine, et verte in sanguine.
