'Saith' in the Bible

For the oppression of the poor, for the sighing of the needy, now will I arise, saith the LORD; I will set him in safety from him that puffeth at him.

{To the chief Musician, A Psalm of David the servant of the LORD.} The transgression of the wicked saith within my heart, that there is no fear of God before his eyes.

But unto the wicked God saith, What hast thou to do to declare my statutes, or that thou shouldest take my covenant in thy mouth?
