Man should look upon the birth of a daughter as a blessing from the Lord.--Gen. Rabba 26.
For seven days the Lord mourned (or deplored) the necessity of destroying His creatures by the deluge.--Gen. Rabba 27.
God will wipe away tears from off all faces (Isa. 25. 8). This means from the faces of non-Jews as well as Jews.--Gen. Rabba 26.
The sexes of both man and the lower animals were meant to be separated in the ark during the deluge. This is clear from the way in which they entered the ark: first Noah and his three sons went in, and then their wives separately (Gen. 7. 7). But when they came out of the ark after the flood, God commanded Noah, 'Go out of the ark, thou and thy wife, thy sons and their wives' (Gen. 8. 16), thus putting the sexes together again. Ham among the human beings, and the dog among the lower animals, disregarded this injunction and did not separate from the opposite sex in the ark. The dog received a certain punishment, and Ham became a black man; just as when a man has the audacity to coin the king's currency in the king's own palace his face is blackened as a punishment and his issue is declared counterfeit --Gen. Rabba 37-
