'Mayest' in the Bible

And Philip said, If thou believest with all thy heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God.

And Ananias departed, and entered into the house; and laying his hands on him said, Brother Saul, the Lord, even Jesus, who appeared unto thee in the way which thou camest, hath sent me, that thou mayest receive thy sight, and be filled with the Holy Spirit.
