  21 H3068 Yahweh H559 said H4872 to Moses, H3212 "When you go H7725 back H4714 into Egypt, H7200 see H6213 that you do H6440 before H6547 Pharaoh H4159 all the wonders H7760 which I have put H3027 in your hand, H2388 but I will harden H3820 his heart H5971 and he will not let the people H7971 go.
  22 H559 You shall tell H6547 Pharaoh, H559 ‘Thus says H3068 Yahweh, H3478 Israel H1121 is my son, H1060 my firstborn,
  23 H559 and I have said H1121 to you, "Let my son H7971 go, H5647 that he may serve H3985 me;" and you have refused H7971 to let him go. H2026 Behold, I will kill H1121 your son, H1060 your firstborn.'"
