Parallel
Exodus 4:9
Clementine Vulgate · Berean Standard Bible
Quod si nec duobus quidem his signis crediderint, neque audierint vocem tuam : sume aquam fluminis, et effunde eam super aridam, et quidquid hauseris de fluvio, vertetur in sanguinem.
But if they do not believe even these two signs or listen to your voice, take some water from the Nile and pour it on the dry ground. Then the water you take from the Nile will become blood on the ground.”
