Parallel
Exodus 7:17
Swete's Septuagint · Berean Standard Bible
τάδε λέγει κύριος Ἐν τούτῳ γνώσῃ ὅτι ἐγὼ κύριος· ἰδοὺ ἐγὼ τύπτω τῇ ῥάβδῳ τῆ ἐν τῇ χειρί μου ἐπὶ τὸ ὕδωρ τὸ ἐν τῷ ποταμῷ. καὶ μεταβαλεῖ εἰς αἶμα·
This is what the LORD says: By this you will know that I am the LORD. Behold, with the staff in my hand I will strike the water of the Nile, and it will turn to blood.
