'Walking' in the Bible

The wise man's eyes are in his head, but the foolish man goes walking in the dark; but still I saw that the same event comes to them all.

What have the wise more than the foolish? and what has the poor man by walking wisely before the living?

And when the foolish man is walking in the way, he has no sense and lets everyone see that he is foolish.

I have seen servants on horses, and rulers walking on the earth as servants.
