CKJV_Strongs(i)
  20 H4872 And Moses H3947 took H802 his wife H1121 and his sons, H7392 and set H2543 them upon a donkey, H7725 and he returned H776 to the land H4714 of Egypt: H4872 and Moses H3947 took H4294 the rod H430 of God H3027 in his hand.
  21 H3068 And the Lord H559 said H4872 unto Moses, H3212 When you go H7725 to return H4714 into Egypt, H7200 see H6213 that you do H4159 all those wonders H6440 before H6547 Pharaoh, H7760 which I have put H3027 in your hand: H2388 but I will harden H3820 his heart, H5971 that he shall not let the people H7971 go.
  22 H559 And you shall say H6547 unto Pharaoh, H559 Thus says H3068 the Lord, H3478 Israel H1121 is my son, H1060 even my firstborn:
  23 H559 And I say H1121 unto you Let my son H7971 go, H5647 that he may serve H3985 me: and if you refuse H7971 to let him go, H2026 behold, I will kill H1121 your son, H1060 even your firstborn.
  24 H1870 And it came to pass by the way H4411 in the inn, H3068 that the Lord H6298 met H1245 him, and sought H4191 to kill him.
  25 H6855 Then Zipporah H3947 took H6864 a sharp stone, H3772 and cut off H6190 the foreskin H1121 of her son, H5060 and cast H7272 it at his feet, H559 and said, H1818 Surely a bloody H2860 husband are you to me.
