The number SEVEN is the most prominent number in the entire bible. The word SEVEN (or derivatives such as SEVENTH or SEVENTY) appear 562 times throughout God’s word. It is clear that its frequent emphasis makes this number especially significant.
Beyond its numerical value and frequency, the number seven’s significance can be found in its Hebrew meaning and derivative.
“The Hebrew language is structured such that most words are based on three-consonant root words. Adding vowels to these root words produces other derived words that have different meanings, and yet these derived words remain related because they share the same root word.”
In the Bible, the word seven symbolically represents wholeness, completeness, abundance, and fullness in its context numerous times (Gen 4:15) (Ex 21:2) (Matt 18:22) (2 Kings 5:10) (Joshua 6:15) (Rev 15:1).
While on several occasions SEVEN is used to represent wholeness, completeness, abundance, and fullness in its context, of course many times the word seven really only represents its numerical significance and needs no deeper evaluation.
Additionally, when we see a series of seven things, the final (seventh) thing is often “special” in some way—different from the first six. We see this in creation, when God worked for the first six days, but rested on the seventh day and declared that day holy. In several cases, we can also see this “special seventh” aspect in Revelation.
The name Seventh Salvation is used to represent the wholeness and abundance of God’s grace and salvation offered to those who believe in him. The number 7 itself has no numerical value in this context and should not be misunderstood to represent anything except the wholeness of God’s salvation that we adopt as believers.
