In addition to these examples, and there are many more, the Almighty has blessed each seventh portion of time in The Sacred Calendar: the The Seventh Day of the Week, the seventh year and also the seventh thousanth year period referred to by Bible students as the Millennium. Together with the Feasts of the God of Israel these all express the concept of totality, maturity, holiness and absolute perfection.
To us in A Voice In The Wilderness - Canada, the triple sevens (777) numerically symbolize Yahweh, the Father of Yeshua the Messiah. He is the pinnacle of perfection, power and purity. The number (777) may also be the numeric value of some word or group of words: we do not know.
Satan has hijacked this number and uses it in all kinds of bizarre ways; but as far as Scripture is concerned, seven is the number of perfection and holiness. To us in A Voice In The Wilderness, the number (777) numerically expresses the Almighty's Truth as regards His (7)th day Sabbath, His (7) annual Sabbaths, His (7)th year Sabbath and His (7)th thousand year Sabbath - the millennium. We could go further and write (7777777) - ad infinitum, or, (70 times 7) with each additional seven representing another perfect revelation of His character: but (777) will do for the time being.
By contrast the treble sixes - 666 - represent Satan the perfection of imperfection: the unholy and immature one: the one who will always fall short of Yahweh's moral stature just as the number 6 will always fall short of the number 7. Perhaps that is why Satan seeks to abolish every sacred seventh portion of time in the calendar of the Almighty: because his evil mind is totally incapable of ever matching the majesty, might and maturity of Yahweh the Holy One of Israel.
