'Whose' in the Bible

Now Naomi had a kinsman of her husband, a man of great wealth, of the family of Elimelech, whose name was Boaz.

And Ruth the Moabitess said to Naomi, “Please let me go to the field and glean among the ears of grain after one in whose sight I may find favor.” And she said to her, “Go, my daughter.”

Then Boaz said to his servant who was in charge of the reapers, “Whose young woman is this?”

May the Lord reward your work, and your wages be full from the Lord, the God of Israel, under whose wings you have come to seek refuge.”

Now is not Boaz our kinsman, with whose maids you were? Behold, he winnows barley at the threshing floor tonight.
