found something good to explain it actually

What follows is that incomplete table of numbers and their Biblical meanings. I must disclaim, however, that these are the only meanings. I have come against some contradictions when looking up the meanings of some numbers. Don't take any of these numbers to the bank unless you've confirmed it with at least the "Adequate Witness" number, two.
Some examples from The Companion Bible:
FOUR - Denotes creative works, and always has reference to the material creation, as pertaining to the earth, and things "under the sun", and things terrestrial.
SEVEN - Denotes spiritual perfection. It is the hall-mark of the Holy Spirit's work. He is the Author of God's Word, and seven is stamped on it as the water mark is seen in the manufacture of paper. He is the Author and Giver of life; and seven is the number which regulates every period of Incubation and Gestation, in insects, birds, animals, and man.
EIGHT - Denotes resurrection, regeneration; a new beginning or commencement. The eighth is a new first. Hence the octave in music, color, days of the week. It is the number which has to do with the Lord, Who rose on the eighth, or new "first-day". This is, therefore, the Dominical number. By Gematria (the addition of the numerical value of the letters together) the Greek letters for Jesus makes the numbers 888. It, or its multiple is impressed on all that has to do with the Lord's Names, the Lord's People, and the Lord's works.
