Nine in the third place means:

There is no skin on his thighs,
And walking comes hard.

No great mistake is made.

There is a temptation to fall in with the evil element offering itself-a very dangerous situation. Fortunately circumstances prevent this; one would like to do it, but cannot. This leads to painful indecision in behavior. But if we gain clear insight into the danger of the situation, we shall at least avoid more serious mistakes.
