Gestation Of God's Creation

The gestation of God's creation are related to a "seven day" principle. The number 7 signifies perfection.

mouse is 21 days (3x7)
hen is 21 days (3x7)
rat is 28 days (4x7)
duck is 42 days (6x7)
cat is 56 days (8x7)
dog is 63 days (9x7)
lion is 98 days (14x7)
sheep is 147 days (21x7)
man is 280 days (40x7)

However, man appears to be made on the "seven-day" principle. Man's pulse beats on the seven-day principle, for the doctors point out that for six days out of the seven, it beats faster in the morning than in the evening, while on the seventh day it beats slower.
