'Whose' in the Bible

And Ruth the Moabitess said to Naomi, Now let me go into the field and take up the heads of grain after him in whose eyes I may have grace. And she said to her, Go, my daughter.

Then Boaz said to his servant who was in authority over the cutters, Whose girl is this?

The Lord give you a reward for what you have done, and may a full reward be given to you by the Lord, the God of Israel, under whose wings you have come to take cover.

And now, is there not Boaz, our relation, with whose young women you were? See, tonight he is separating the grain from the waste in his grain-floor.
