'Dost' in the Bible

And Boaz saith unto Ruth, 'Hast thou not heard, my daughter? go not to glean in another field, and also, pass not over from this, and thus thou dost cleave to my young women:

And Boaz answereth and saith to her, 'It hath thoroughly been declared to me all that thou hast done with thy mother-in-law, after the death of thy husband, and thou dost leave thy father, and thy mother, and the land of thy birth, and dost come in unto a people which thou hast not known heretofore.

And Ruth the Moabitess saith, 'Also he surely said unto me, Near the young people whom I have thou dost cleave till they have completed the whole of the harvest which I have.'

and it cometh to pass when he lieth down, that thou hast known the place where he lieth down, and hast gone in, and uncovered his feet, and lain down, -- and he doth declare to thee that which thou dost do.'

And she saith, 'These six measures of barley he hath given to me, for he said, Thou dost not go in empty unto thy mother-in-law.'

And she saith, 'Sit still, my daughter, till thou dost know how the matter falleth, for the man doth not rest except he hath completed the matter to-day.'

and I said, I uncover thine ear, saying, Buy before the inhabitants, and before the elders of my people; if thou dost redeem -- redeem, and if none doth redeem -- declare to me, and I know, for there is none save thee to redeem, and I after thee.' And he saith, I redeem it.'
