The sons of Judah; Er, and Onan, and Shelah: which three were born unto him of the daughter of Shua the Canaanitess. And Er, the firstborn of Judah, was evil in the sight of the Lord; and he slew him.

Be not over much wicked, neither be thou foolish: why shouldest thou die before thy time?

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

Then shall his brother’s wife come unto him in the presence of the elders, and loose his shoe from off his foot, and spit in his face, and shall answer and say, So shall it be done unto that man that will not build up his brother’s house.

And when the people complained, it displeased the Lord: and the Lord heard it; and his anger was kindled; and the fire of the Lord burnt among them, and consumed them that were in the uttermost parts of the camp.
