The Meaning of Numbers: The Number 28
The number 28 derives part of its meaning from the fact that it is the product of 7 (a perfect numeral) and 4.

Appearances of the number twenty-eight
A set of ten curtains God commanded to be made for his wilderness tabernacle had to be made of the finest twined linen (Exodus 26:1). Each curtain in this set had to be 28 cubits long and 4 cubits wide. If we assume the cubit used was a conservative 18 inches (45.7 centimeters), this meant each curtain was 42 feet (12.8 meters) long and 6 feet (1.8 meters) wide (Exodus 26:2, 36:9)!
The bloody number 28
King Jehu, a mostly bad king who ruled over the Kingdom of Israel, governed for 28 official years (27 actual years from 841 to 814 B.C., see 2Kings 10:36).
He is unique among the kings of Israel and Judah, as his reign began in the bloodiest way possible. He was commissioned by God, through Elisha, to destroy all those of the household of evil King Ahab. In fulfillment of Elijah's prophecy, Jehu had all of Ahab's seventy sons killed and their heads stacked in two piles at Jezreel's gate (2Kings 10:1 - 11). He also killed in Jezreel all the leaders, pagan priests, and kinsfolks that were connected to Ahab.
Additionally, He had evil Jezebel, the wife of King Ahab, thrown out of a tower window and killed. In fulfillment of yet another of Elijah's prophecies, her dead body was then torn to pieces by dogs where only her skull, feet and the palms of her hands remained (2Kings 9:30 - 37).
Jehu, as if all the above wasn't enough, in the same year he took care of Ahab's household he also slew his predecessor King Joram of Israel (a son of Ahab and Jezebel) and King Ahaziah of Judah (2Kings 9:24, 27 - 28).
