⁴ For in seven days I am going to cause it to rain on the earth for forty days and forty nights; and I will destroy (blot out, wipe away) every living thing that I have made from the surface of the earth.” ⁵ So Noah did all that the Lord commanded him.^(A)

⁶ Noah was six hundred years old when the flood (deluge) of water came on the earth [covering all of the land].
