'Whom' in the Bible

And her mother in law said unto her, Where hast thou gleaned to day? and where wroughtest thou? blessed be he that did take knowledge of thee. And she shewed her mother in law with whom she had wrought, and said, The man's name with whom I wrought to day is Boaz.

Then went Boaz up to the gate, and sat him down there: and, behold, the kinsman of whom Boaz spake came by; unto whom he said, Ho, such a one! turn aside, sit down here. And he turned aside, and sat down.

And let thy house be like the house of Pharez, whom Tamar bare unto Judah, of the seed which the LORD shall give thee of this young woman.
