And the Lord heard the voice of your words. I have shown elsewhere what is meant by God's hearing, i.e., that nothing can be concealed from Him, but that tie will take account of and judge all our words and deeds And this is worthy of our observation; for men would never dare to murmur against Him, unless they promised themselves impunity from His not being present. Secondly, we learn from hence, that God, who is a just Judge, does not proceed hastily and without cause to inflict punishment on men, and that He does not manifest severity without a full examination of the case. He, therefore, means that they deprived themselves of their assured inheritance, when they were close upon receiving it, through their own rebellion and depravity.

The Lord - was wroth - That is, his justice was incensed, and he evidenced his displeasure against you; and he could not have been a just God if he had not done so.

And the Lord heard the voice of your words,.... Of their murmurings against Moses and Aaron, and of their threatenings to them, Joshua and Caleb, and of their impious charge of hatred of them to God for bringing them out of Egypt, and of their rash wishes that they had died there or in the wilderness, and of their wicked scheme and proposal to make them a captain, and return to Egypt again:
and was wroth, and sware; by his life, himself; see Numbers 14:28,
saying; as follows.

the Lord heard the voice of your words, and was wroth--In consequence of this aggravated offense (unbelief followed by open rebellion), the Israelites were doomed, in the righteous judgment of God, to a life of wandering in that dreary wilderness till the whole adult generation had disappeared by death. The only exceptions mentioned are Caleb and Joshua, who was to be Moses' successor.
