Biblical Understanding based on the Record of Scripture
YHVH created the sun and the moon and set them in the heavens, in part, to show when to observe His Festivals. The date listed on this calendar for the start of the 1st month and the 7th month is based on the first projected sighting, after sunset, of the renewing of the light of the moon.
Ecclesiastes 4:9,10,12 NKJV
Two are better than one, because they will have good reward for their labor.
For if they fall, one will lift up his companion. But woe to him that is alone when he falls, for he has no one to help him up.
Though one may be overpowered by another, two can withstand him. And a threefold cord is not quickly broken.
