'Seven' in the Bible

For behold, the stone that I have laid before Joshua upon one stone are seven eyes; behold, I will engrave the graving thereof, saith Jehovah of hosts, and I will remove the iniquity of this land in one day.

And he said unto me, What seest thou? And I said, I see, and behold, a lamp-stand all of gold, with a bowl upon the top of it, and its seven lamps thereon, seven lamps and seven pipes to the lamps, which are upon the top thereof;

For who hath despised the day of small things? Yea, they shall rejoice even those seven and shall see the plummet in the hand of Zerubbabel: these are the eyes of Jehovah, which run to and fro in the whole earth.
