Genesis 4:6 YLT

⁴  and Abel, he hath brought, he also, from the female firstlings of his flock, even from their fat ones; and Jehovah looketh unto Abel and unto his present,

⁵  and unto Cain and unto his present He hath not looked; and it is very displeasing to Cain, and his countenance is fallen.

⁶  And Jehovah saith unto Cain, 'Why hast thou displeasure? and why hath thy countenance fallen?

⁷  Is there not, if thou dost well, acceptance? and if thou dost not well, at the opening a sin-offering is crouching, and unto thee its desire, and thou rulest over it.'

⁸  And Cain saith unto Abel his brother, ''Let us go into the field;'' and it cometh to pass in their being in the field, that Cain riseth up against Abel his brother, and slayeth him.
