The rare Blood Moon Tetrads of 2014--15 are exactly 2,598 days from the (4) Blood Moons of 2021 and 2022. See the graphic.
Strongs Hebrew 2598 is "Dedication" perhaps pointing to the Feast of Dedication which begins on December 18th.... and also exactly 40 days from the last Blood Moon of November 8th, 2022. This also seems to fit Mt. 24:20 "that your flight not be on the Sabbath , nor in Winter " as the Sabbath is the 17th and Winter begins on December 21......
December 18th ?
