It is an unusual fact that the subjects of God's spring holy days and firstborns appear in the same contexts. Here is what this means to us.

The priests saw the glory of God after seven days of consecration. Similarly, after 7000 years of human history, the Eighth Millennium will dawn.

The number eight signifies a new start with abundance abundance following a period of time (a week, seven years, or a millennium) of preparatory activity.

The firstborn privileges indicate prominence, carrying the birthright promises. In the New Testament, the firstborn did not always correspond to actual birth order.
