Adam Clarke on Job 4:12

Now a thing was secretly brought to me - To give himself the more authority, he professes to have received a vision from God, by which he was taught the secret of the Divine dispensations in providence; and a confirmation of the doctrine which he was now stating to Job; and which he applied in a different way to what was designed in the Divine communication.

Mine ear received a little thereof - Mr. Good translates, "And mine ear received a whisper along with it." The apparition was the general subject; and the words related Job 4:17, etc., were the whispers which he heard when the apparition stood still.
