INTRODUCTION TO GENESIS 38 This chapter is wholly taken up with matters relating to Judah, the fourth son of Jacob, from whom the Jews have their name, and from whom Christ sprung: it treats of his marriage with a Canaanitess, his children by her, their character and end, Gen 38:1; of his incest with his daughter-in-law, though unknown by him, Gen 38:12; of his resentment against her, when he heard she was with child, and his confusion when he found it was by himself, Gen 38:24; and of the birth of twins by her, named Pharez and Zarah, Gen 38:27.
