'Thine' in the Bible

Be thou watchful, and establish the things that remain, which were ready to die: for I have found no works of thine perfected before my God.

I counsel thee to buy of me gold refined by fire, that thou mayest become rich; and white garments, that thou mayest clothe thyself, and that the shame of thy nakedness be not made manifest; and eyesalve to anoint thine eyes, that thou mayest see.
