'Forgive' in the Bible

And now, forgive, I pray you, my sin only this time, and intreat Jehovah your God that he may take away from me this death only!

Be careful in his presence, and hearken unto his voice: do not provoke him, for he will not forgive your transgressions; for my name is in him.

And now, if thou wilt forgive their sin ... but if not, blot me, I pray thee, out of thy book that thou hast written.
