But murmured in their tents - Numbers 14:2, Numbers 14:27. They complained of Moses; they complained of their food; they complained of the hardships of their journey; they complained of God. They did this when "in their tents;" when they had a comfortable home; when safe; when provided for; when under the direct divine protection and care. So people often complain: perhaps oftener when they have "many" comforts than when they have "few."

But murmured in their tents,.... Throughout their tents; the murmuring was general; they murmured often; but what is here referred to seems to be their murmuring upon the report of the spies, Numbers 14:2. To murmur against God and his providence is a very great evil; and which generally proceeds on one or other of these two things; either because men have not so much of the good things of this world as others have; or because they endure more afflictions, and so are ready to charge the ways of God with inequality; not considering that God is a Sovereign, and may do with his own what he pleases; and that they are deserving of nothing at his hands; and that their punishment or chastisement is less than their sins deserve.
And hearkened not unto the voice of the Lord; to go up and possess the land; they disbelieved his word, and were disobedient to his command. The use the apostle makes of this, see Hebrews 3:7, and of their other provocations, of their lust, idolatry, fornication, tempting of God, and murmuring against him, see 1-Corinthians 10:6.

The voice - To God's command, that they should boldly enter into it.
