ASV_Strongs(i)
  10 H4872 And Moses H175 and Aaron H935 went in H6547 unto Pharaoh, H6213 and they did H3068 so, as Jehovah H6680 had commanded: H175 and Aaron H7993 cast down H4294 his rod H6440 before H6547 Pharaoh H6440 and before H5650 his servants, H8577 and it became a serpent.
  11 H6547 Then Pharaoh H7121 also called H2450 for the wise men H3784 and the sorcerers: H2748 and they also, the magicians H4714 of Egypt, H6213 did H3651 in like manner H3858 with their enchantments.
  12 H7993 For they cast down H376 every man H4294 his rod, H8577 and they became serpents: H175 but Aaron's H4294 rod H1104 swallowed up H4294 their rods.
  13 H6547 And Pharaoh's H3820 heart H2388 was hardened, H8085 and he hearkened H3068 not unto them; as Jehovah H1696 had spoken.
  14 H3068 And Jehovah H559 said H4872 unto Moses, H6547 Pharaoh's H3820 heart H3515 is stubborn, H3985 he refuseth H5971 to let the people H7971 go.
  15 H3212 Get H6547 thee unto Pharaoh H1242 in the morning; H3318 lo, he goeth out H4325 unto the water; H5324 and thou shalt stand H2975 by the river's H8193 brink H7125 to meet H4294 him; and the rod H2015 which was turned H5175 to a serpent H3947 shalt thou take H3027 in thy hand.
