'Whose' in the Bible

“From Ephraim those whose root is in Amalek came down,Following you, Benjamin, with your peoples;From Machir commanders came down,And from Zebulun those who wield the staff of office.

and I said to you, “I am the Lord your God; you shall not fear the gods of the Amorites in whose land you live. But you have not obeyed Me.”’”

There was a certain man of Zorah, of the family of the Danites, whose name was Manoah; and his wife was barren and had borne no children.

After this it came about that he loved a woman in the valley of Sorek, whose name was Delilah.

Now there was a man of the hill country of Ephraim whose name was Micah.
