Genesis 38:1-5

1And it came about at that time, that Judah 1departed from his brothers and 2visited a certain 3Adullamite, whose name was Hirah. 2Judah saw there a daughter of a certain Canaanite whose name was 4Shua; and he took her as a wife and had relations with her. 3And she conceived and gave birth to a son, and he named him 5Er. 4Then she conceived again and gave birth to a son, and she named him 6Onan. 5She gave birth to yet another son and named him 7Shelah; and it was at Chezib 8that she gave birth to him.
