Young's Literal Translation

⁴ for after other seven days I am sending rain on the earth forty days and forty nights, and have wiped away all the substance that I have made from off the face of the ground.'

⁶ and Noah [is] a son of six hundred years, and the deluge of waters hath been upon the earth.
