'Walk' in the Bible

Wherefore Jehovah the God of Israel saith, I said indeed, Thy house and the house of thy father should walk before me for ever. But now Jehovah saith, Be it far from me; for them that honour me I will honour, and they that despise me shall be lightly esteemed.

And I will raise up for myself a faithful priest, who shall do according to what is in my heart and in my mind; and I will build him a sure house; and he shall walk before mine anointed continually.

and said to him, Behold, thou art become old, and thy sons walk not in thy ways: now appoint us a king to judge us, like all the nations.
