'Whose' in the Bible

Ruth the Moabitess said to Naomi, "Let me now go to the field, and glean among the ears of grain after him in whose sight I shall find favor." She said to her, "Go, my daughter."

Then Boaz said to his servant who was set over the reapers, "Whose young lady is this?"

May Yahweh repay your work, and a full reward be given you from Yahweh, the God of Israel, under whose wings you have come to take refuge."

Now isn't Boaz our kinsman, with whose maidens you were? Behold, he winnows barley tonight in the threshing floor.
