And he lifted up his eyes, and saw his brother Benjamin, his mother's son, and said, Is this your younger brother, of whom ye spake unto me? And he said, God be gracious unto thee, my son.Benjamin is Joseph's only full brother (Genesis 35:24). Some biblical scholars insist that Benjamin was born after Joseph was sold into Egypt. However, I believe that opinion is easily refuted with Genesis 35:22. In the end, it does not make a big difference.
