For as in those days which were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered into the ark,

κατακλυσμοῦ, kataklusmou “flood,”

and they knew not until the flood came, and took them all away; so shall be the coming of the Son of man.

κατακλυσμὸς kataklusmos “flood”

They ate, they drank, they married, they were given in marriage, until the day that Noah entered into the ark, and the flood came, and destroyed them all.

κατακλυσμὸς kataklusmos “flood”

and spared not the ancient world, but preserved Noah with seven others, a preacher of righteousness, when he brought a flood upon the world of the ungodly;

κατακλυσμὸν kataklusmon “[the] flood upon”
