Numbers 14:39-45 - Israel Defeated In Battle
39 And Moses spoke words to all the {Israelites}, and the people mourned greatly. 40 They rose early in the morning and went to the top of the mount, saying, "Here we are. We will go up to the place that Yahweh said, because we have sinned."
41 But Moses said, "Why [are] you going against the command of Yahweh? It will not succeed. 42 You should not go up because Yahweh is not in your midst; do not let yourselves be defeated in the presence of your enemies, 43 because the Amalekites and the Canaanites [are] there {before you}, and you will fall by the sword; because you have turned [back] from Yahweh, and Yahweh will not be with you."
44 But they dared to go to the top of the mountain, and the ark of the covenant of Yahweh and Moses did not depart from the midst of the camp. 45 So the Amalekites and the Canaanites who were living on the mountain descended, and they beat them down, up to Hormah.
