Here is the Greek for the word translated as "hearing" and "heard."

It can mean to hear with the ear, but also can mean to understand, comprehend, consider, or perceive.
No contradiction.
We have barred the gates but cannot hold them for long. The ground shakes, drums... drums in the deep. We cannot get out. A shadow lurks in the dark. We can not get out... they are coming.
"...Awake thou that sleepest, and arise from the dead, and Christ shall give thee light. See then that ye walk circumspectly, not as fools, but as wise, Redeeming the time, because the days are evil." - Ephesians 5:14-17
