Genesis 6:12-15 Catholic Public Domain Version (CPDV)

12. And when God had seen that the earth had been corrupted, (indeed, all flesh had corrupted its way upon the earth)

13. he said to Noah: "The end of all flesh has arrived in my sight. The earth has been filled with iniquity by their presence, and I will destroy them, along with the earth.

14. Make yourself an ark from smoothed wood. You shall make little dwelling places in the ark, and you shall smear pitch on the interior and exterior.

15. And thus shall you make it: The length of the ark shall be three hundred cubits, its width fifty cubits, and its height thirty cubits.
