'Seven' in the Bible

For consider, the stone that {I set before} Joshua, on one stone [are] seven eyes. Look, {I am going to engrave an inscription on it},' {declares} Yahweh of hosts, 'and I will remove the guilt of that land in a single day.

And he said to me, "What do you see?" And I said, "I see, and look, {a lampstand all of gold}, and a bowl [was] on its top, and its seven lamps on it, and seven lips on [each of] the lamps that [are] on its top.

For whoever has despised the day of small [things] will rejoice and will see the {plumb line} in the hand of Zerubbabel." These seven [are] the eyes of Yahweh which [are] ranging {throughout the whole earth}.
