'Seven' in the Bible

For behold, the stone which I have set before Joshua; on that one stone are seven eyes (symbolizing infinite intelligence, omniscience). Behold, I will engrave an inscription on it,’ declares the Lord of hosts, ‘and I will remove the wickedness and guilt of this land in a single day.

He said to me, “What do you see?” I said, “I see, and behold, a lampstand all of gold, with its bowl [for oil] on the top of it and its seven lamps on it with seven spouts belonging to each of the lamps which are on the top of it.

Who [with reason] despises the day of small things (beginnings)? For these seven [eyes] shall rejoice when they see the plumb line in the hand of Zerubbabel. They are the eyes of the Lord which roam throughout the earth.”
