'Voice of the Lord' in the Bible

And crying out to the man of God who came from Judah, he said, The Lord says, Because you have gone against the voice of the Lord, and have not done as you were ordered by the Lord,

Then said he unto him, Because thou hast not obeyed the voice of the LORD, behold, as soon as thou art departed from me, a lion shall slay thee. And as soon as he was departed from him, a lion found him, and slew him.
