40 Early the next morning they set out for the highest point in the hill country, saying, "Now we are ready to go up to the land the Lord promised. Surely we have sinned!" 41 But Moses said, "Why are you disobeying the Lord's command? This will not succeed! 42 Do not go up, because the Lord is not with you. You will be defeated by your enemies, 43 for the Amalekites and the Canaanites will face you there. Because you have turned away from the Lord, he will not be with you and you will fall by the sword." 44 Nevertheless, in their presumption they went up toward the highest point in the hill country, though neither Moses nor the ark of the Lord's covenant moved from the camp. 45 Then the Amalekites and the Canaanites who lived in that hill country came down and attacked them and beat them down all the way to Hormah.

Commentary on Numbers 14:40-45

(Read Numbers 14:40-45)

Some of the Israelites were now earnest to go forward toward Canaan. But it came too late. If men would but be as earnest for heaven while their day of grace lasts, as they will be when it is over, how well would it be for them! That which has been duty in its season, when mistimed, may be turned into sin. Those who are out of the way of their duty, are not under God's protection, and go at their peril. God bade them go, and they would not; he forbade them, and they would go. Thus is the carnal mind enmity against God. They had distrusted God's strength; they now presume upon their own without his. And the expedition fails accordingly; now the sentence began to be executed, that their carcases should fall in the wilderness. That affair can never end well, which begins with sin. The way to obtain peace with our friends, and success against our enemies, is, to have God, as our Friend, and to keep in his love. Let us take warning from the fate of Israel, lest we perish after the same example of unbelief. Let us go forth, depending on God's mercy, power, promise, and truth; he will be with us, and bring our souls to everlasting rest.
