19And YhwhH3068 spakeH559 unto MosesH4872, SayH559 unto AaronH175, TakeH3947 thy rodH4294, and stretch outH5186 thine handH3027 upon the watersH4325 of EgyptH4714, upon their streamsH5104, upon their riversH2975, and upon their pondsH98, and upon all their poolsH4723 of waterH4325, that they may become bloodH1818; and that there may be bloodH1818 throughout all the landH776 of EgyptH4714, both in vessels of woodH6086, and in vessels of stoneH68.1 20And MosesH4872 and AaronH175 didH6213 so, as YhwhH3068 commandedH6680; and he lifted upH7311 the rodH4294, and smoteH5221 the watersH4325 that were in the riverH2975, in the sightH5869 of PharaohH6547, and in the sightH5869 of his servantsH5650; and all the watersH4325 that were in the riverH2975 were turnedH2015 to bloodH1818.
