Genesis 6:2 YLT

¹  And it cometh to pass that mankind have begun to multiply on the face of the ground, and daughters have been born to them,

²  and sons of God see the daughters of men that they 'are' fair, and they take to themselves women of all whom they have chosen.

³  And Jehovah saith, 'My Spirit doth not strive in man -- to the age; in their erring they 'are' flesh:' and his days have been an hundred and twenty years.

⁴  The fallen ones were in the earth in those days, and even afterwards when sons of God come in unto daughters of men, and they have borne to them -- they 'are' the heroes, who, from of old, 'are' the men of name.
