'Mayest' in the Bible

Jehovah do so to Jonathan, and more also, should it please my father to do thee evil, if I disclose it not unto thee, and send thee away, that thou mayest go in peace: and Jehovah be with thee, as he hath been with my father.

And Samuel said to Saul, Why hast thou disquieted me, to bring me up? And Saul answered, I am sore distressed; for the Philistines make war against me, and God is departed from me, and answereth me no more, neither by prophets, nor by dreams: therefore I have called thee, that thou mayest make known unto me what I shall do.

Now therefore, I pray thee, hearken thou also unto the voice of thy handmaid, and let me set a morsel of bread before thee; and eat, that thou mayest have strength, when thou goest on thy way.
