'Mayest' in the Bible

Take a harp, go about the city, thou forgotten harlot! Make sweet melody, sing many songs, that thou mayest be remembered.

Put me in remembrance, let us plead together; rehearse thine own cause, that thou mayest be justified.

and I will give thee the treasures of darkness, and hidden riches of secret places; that thou mayest know that I, Jehovah, who call thee by name, am the God of Israel.

Stand now with thine enchantments and with the multitude of thy sorceries, wherein thou hast laboured from thy youth; if so be thou shalt be able to turn them to profit, if so be thou mayest cause terror.

and he saith, It is a small thing that thou shouldest be my servant to raise up the tribes of Jacob, and to restore the preserved of Israel; I have even given thee for a light of the nations, that thou mayest be my salvation unto the end of the earth.
