Exodus 7:17-20

17ThusH3541 saith Jehovah, In this thou shalt knowH3045 that I am Jehovah: behold, I will smite with the rodH4294 that is in my handH3027 upon the watersH4325 which are in the riverH2975, and they shall be turnedH2015 to bloodH1818. 18And the fishH1710 that are in the riverH2975 shall dieH4191, and the riverH2975 shall becomeH887 foul; and the EgyptiansH4713 shall loathe to drinkH8354 waterH4325 from the riverH2975. 19And Jehovah saidH559 unto MosesH4872, SayH559 unto AaronH175, TakeH3947 thy rodH4294, and stretchH5186 out thy handH3027 over the watersH4325 of EgyptH4714, over their riversH5104, over their streams, and over their poolsH98, and over all their pondsH98 of waterH4325, that they may becomeH1961 bloodH1818; and there shall beH1961 bloodH1818 throughout all the landH776 of EgyptH4714, both in vessels of woodH6086 and in vessels of stoneH68.

20And MosesH4872 and AaronH175 did soH3651, as Jehovah commandedH6680; and he liftedH7311 up the rodH4294, and smote the watersH4325 that were in the riverH2975, in the sight of PharaohH6547, and in the sight of his servantsH5650; and all the watersH4325 that were in the riverH2975 were turnedH2015 to bloodH1818.
