'Whom' in the Bible

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

Now Boaz went up to the gate, and sat him down there: and, behold, the near 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 Perez, whom Tamar bare unto Judah, of the seed which Jehovah shall give thee of this young woman.
