Six in the third place means

Forward and backward, abyss on abyss.

In danger like this, pause at first and wait,

Otherwise you will fall into a pit in the abyss.

Do not act this way.

Here every step, forward or backward, leads into danger. Escape is out of the question. Therefore we must not be misled into action, as a result of which we should only bog down deeper in the danger; disagreeable as it may be to remain in such a situation, we must wait until a way out shows itself.
