'Walk' in the Bible

If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:

But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.

He that saith he abideth in him ought himself also so to walk, even as he walked.

and he who is hating his brother, in the darkness he is, and in the darkness he doth walk, and he hath not known whither he doth go, because the darkness did blind his eyes.
