Genesis 49:8

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.

Then Judah came near unto him, and said, Oh my lord, let thy servant, I pray thee, speak a word in my lord's ears, and let not thine anger burn against thy servant: for thou art even as Pharaoh. My lord asked his servants, saying, Have ye a father, or a brother? And we said unto my lord, We have a father, an old man, and a child of his old age, a little one; and his brother is dead, and he alone is left of his mother, and his father loveth him. And thou saidst unto thy servants, Bring him down unto me, that I may set mine eyes upon him. And we said unto my lord, The lad cannot leave his father: for if he should leave his father, his father would die. And thou saidst unto thy servants, Except your youngest brother come down with you, ye shall see my face no more. And it came to pass when we came up unto thy servant my father, we told him the words of my lord. And our father said, Go again, and buy us a little food. And we said, We cannot go down: if our youngest brother be with us, then will we go down: for we may not see the man's face, except our youngest brother be with us. And thy servant my father said unto us, Ye know that my wife bare me two sons: And the one went out from me, and I said, Surely he is torn in pieces; and I saw him not since: And if ye take this also from me, and mischief befall him, ye shall bring down my gray hairs with sorrow to the grave. Now therefore when I come to thy servant my father, and the lad be not with us; seeing that his life is bound up in the lad's life; It shall come to pass, when he seeth that the lad is not with us, that he will die: and thy servants shall bring down the gray hairs of thy servant our father with sorrow to the grave. For thy servant became surety for the lad unto my father, saying, If I bring him not unto thee, then I shall bear the blame to my father for ever. Now therefore, I pray thee, let thy servant abide instead of the lad a bondman to my lord; and let the lad go up with his brethren. For how shall I go up to my father, and the lad be not with me? lest peradventure I see the evil that shall come on my father.

And the sons of Judah; Er, and Onan, and Shelah, and Pharez, and Zarah: but Er and Onan died in the land of Canaan. And the sons of Pharez were Hezron and Hamul.

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.

For Judah prevailed above his brethren, and of him came the chief ruler; but the birthright was Joseph's:)

In Judah is God known: his name is great in Israel.

For it is evident that our Lord sprang out of Juda; of which tribe Moses spake nothing concerning priesthood.
