CKJV_Strongs(i)
  9 H4872 And Moses H559 said H3091 unto Joshua, H977 Choose us out H582 men, H3318 and go out, H3898 fight H6002 with Amalek: H4279 to morrow H5324 I will stand H7218 on the top H1389 of the hill H4294 with the rod H430 of God H3027 in my hand.
  10 H3091 So Joshua H6213 did H4872 as Moses H559 had said H3898 to him, and fought H6002 with Amalek: H4872 and Moses, H175 Aaron, H2354 and Hur H5927 went up H7218 to the top H1389 of the hill.
  11 H4872 And it came to pass, when Moses H7311 held up H3027 his hand, H3478 that Israel H1396 prevailed: H5117 and when he let down H3027 his hand, H6002 Amalek H1396 prevailed.
  12 H4872 But Moses' H3027 hands H3515 were heavy; H3947 and they took H68 a stone, H7760 and put H3427 it under him, and he sat H175 on it and Aaron H2354 and Hur H8551 stayed up H3027 his hands, H259 the one on the one side, H259 and the other on the other side; H3027 and his hands H530 were steady H935 until the going down H8121 of the sun.
  13 H3091 And Joshua H2522 defeated H6002 Amalek H5971 and his people H6310 with the edge H2719 of the sword.
