'Slayeth' in the Bible

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.

And the LORD said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the LORD set a mark upon Cain, lest any finding him should kill him.
