'Voice' in the Bible

For the children of Israel walked forty years in the wilderness, till all the people that were men of war, which came out of Egypt, were consumed, because they obeyed not the voice of the LORD: unto whom the LORD sware that he would not shew them the land, which the LORD sware unto their fathers that he would give us, a land that floweth with milk and honey.

And Joshua had commanded the people, saying, Ye shall not shout, nor make any noise with your voice, neither shall any word proceed out of your mouth, until the day I bid you shout; then shall ye shout.

And there was no day like that before it or after it, that the LORD hearkened unto the voice of a man: for the LORD fought for Israel.

And said unto them, Ye have kept all that Moses the servant of the LORD commanded you, and have obeyed my voice in all that I commanded you:

And the people said unto Joshua, The LORD our God will we serve, and his voice will we obey.
