"Tzadik in His Times"G‑d instructs Noah the only righteous man in a world consumed by violence and corruption to build an ark, coated within and without with pitch. A great deluge, says G‑d, will wipe out all life from the face of the earth; but the ark will float upon the water, sheltering Noah and his family, and two members (male and female) of each animal species.
In its mouth:
In its mouthis a reference to prayer, because only through praying genuinely to G-d can we hope to be saved.
Make an opening for daylight in the ark(6:16)
Something to think about?!?!?!?!?!
Even if the entire world considers you a Tzadik you should nevertheless think of yourself as if you were sinful(Niddah 30b).
