15 H6547 And it came to pass, when Pharaoh H7185 would hardly [H8689] H7971 let us go [H8763] H3068 , that the LORD H2026 slew [H8799] H1060 all the firstborn H776 in the land H4714 of Egypt H1060 , both the firstborn H120 of man H1060 , and the firstborn H929 of beast H2076 : therefore I sacrifice [H8802] H3068 to the LORD H6363 all that openeth H7358 the matrix H2145 , being males H1060 ; but all the firstborn H1121 of my children H6299 I redeem [H8799] .

15 H6363 Every thing that openeth H7358 the matrix H1320 in all flesh H7126 , which they bring [H8686] H3068 unto the LORD H120 , whether it be of men H929 or beasts H1060 , shall be thine: nevertheless the firstborn H120 of man H6299 shalt thou surely [H8800] H6299 redeem [H8799] H1060 , and the firstling H2931 of unclean H929 beasts H6299 shalt thou redeem [H8799] .
