and they knew not until the flood came, and took them all away; so shall be the coming of the Son of man.
and knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.
And they did not know or understand until the flood came and swept them all away–so will be the coming of the Son of Man. [Gen. 6:5-8; 7:6-24.]
They didn’t know what was happening until the flood came and swept them all away. The coming of the Human One will be like that.
And they did not realize it, until the flood came and took them all away. So also will the advent of the Son of man be.
