'Seven' in the Bible

Notice the stone I have set before Joshua; on that one stone are seven eyes. I will engrave an inscription on it”—this is the declaration of the Lord of Hosts—“and I will take away the guilt of this land in a single day.

He asked me, “What do you see?”I replied, “I see a solid gold lampstand there with a bowl on its top. It has seven lamps on it and seven channels for each of the lamps on its top.

For who scorns the day of small things? These seven eyes of the Lord, which scan throughout the whole earth, will rejoice when they see the plumb line in Zerubbabel’s hand.”
