Genesis 46:12

And she conceived again, and bare a son: and she said, Now will I praise the LORD: therefore she called his name Judah; and left bearing.

And it came to pass at that time, that Judah went down from his brethren, and turned in to a certain Adullamite, whose name was Hirah. And Judah saw there a daughter of a certain Canaanite, whose name was Shuah; and he took her, and went in unto her. And she conceived, and bare a son; and he called his name Er.

Judah, thou art he whom thy brethren shall praise: thy hand shall be in the neck of thine enemies; thy father's children shall bow down before thee. Judah is a lion's whelp: from the prey, my son, thou art gone up: he stooped down, he couched as a lion, and as an old lion; who shall rouse him up? The sceptre shall not depart from Judah, nor a lawgiver from between his feet, until Shiloh come; and unto him shall the gathering of the people be. Binding his foal unto the vine, and his ass's colt unto the choice vine; he washed his garments in wine, and his clothes in the blood of grapes: His eyes shall be red with wine, and his teeth white with milk.

Of Judah; Nahshon the son of Amminadab.

The sons of Judah were Er and Onan: and Er and Onan died in the land of Canaan. And the sons of Judah after their families were; of Shelah, the family of the Shelanites: of Pharez, the family of the Pharzites: of Zerah, the family of the Zarhites. And the sons of Pharez were; of Hezron, the family of the Hezronites: of Hamul, the family of the Hamulites.

And this is the blessing of Judah: and he said, Hear, LORD, the voice of Judah, and bring him unto his people: let his hands be sufficient for him; and be thou an help to him from his enemies.
