'Again' in the Bible

and again, The Lord knoweth the reasonings of the wise that they are vain.

Defraud ye not one the other, except it be by consent for a season, that ye may give yourselves unto prayer, and may be together again, that Satan tempt you not because of your incontinency.

And the eye cannot say to the hand, I have no need of thee: or again the head to the feet, I have no need of you.
