'Mayest' in the Bible

For this let every one that is godly pray unto thee in a time when thou mayest be found: Surely when the great waters overflow they shall not reach unto him.

Against thee, thee only, have I sinned, And done that which is evil in thy sight; That thou mayest be justified when thou speakest, And be clear when thou judgest.

That thou mayest crush them , dipping thy foot in blood, That the tongue of thy dogs may have its portion from thine enemies.

That thou mayest give him rest from the days of adversity, Until the pit be digged for the wicked.

These wait all for thee, That thou mayest give them their food in due season.

But there is forgiveness with thee, That thou mayest be feared.
