And turned their rivers into blood, And their streams, so that they could not drink.

So that their rivers were turned to blood, and they were not able to get drink from their streams.

και μετεβαλεν εις αιμα τους ποταμους αυτων και τους ρυακας αυτων, δια να μη πιωσιν.

And had turned their rivers into blood; and their floods, that they could not drink.
