'Going to and Fro' in the Bible

Now, therefore, lo! the king going to and fro before you, But, I, am old and grey-headed, and, my sons, lo! they are with you, - But, I, have gone to and fro before you from my youth until this day.

But the men were very good to us, and we were not hurt, neither did we miss anything as long as we were going to and fro among them, when we were in the fields.

Now, therefore, this blessing which thy maid-servant hath brought to my lord, let it even be given unto the young men who are going to and fro at the feet of my lord.
