First mention of Peleg =
"And unto Eber (the Regions Beyond) were born two sons: the name of one was Peleg (Division); for in his days was the earth divided; and his brother's name was Joktan (smallness)."
Peleg means Division (of the Earth's continents).
Peleg's Hebrew Strong's number = 6389 (prime)
6389 = (298 x 18) + 1025
day 298 = 10.25 in a non leap year.
