'Seven' in the Bible

Then was Nebuchadnezzar full of fury, and the form of his visage was changed against Shadrach, Meshach, and Abed-nego. He spoke, and commanded that they should heat the furnace seven times more than it was wont to be heated.

Let his heart be changed from man's, and let a beast's heart be given unto him; and let seven times pass over him.

And whereas the king saw a watcher and a holy one coming down from the heavens, and saying, Hew the tree down, and destroy it; nevertheless leave the stump of its roots in the earth, even with a band of iron and brass, in the tender grass of the field; and let it be bathed with the dew of heaven, and let his portion be with the beasts of the field, till seven times pass over him:

They shall drive thee from men, and thy dwelling shall be with the beasts of the field, and they shall make thee to eat grass as oxen, and thou shalt be bathed with the dew of heaven; and seven times shall pass over thee, till thou know that the Most High ruleth over the kingdom of men, and giveth it to whomsoever he will.

and they shall drive thee from men, and thy dwelling shall be with the beasts of the field; they shall make thee to eat grass as oxen, and seven times shall pass over thee, until thou know that the Most High ruleth over the kingdom of men, and giveth it to whomsoever he will.

Know therefore and understand: From the going forth of the word to restore and to build Jerusalem unto Messiah, the Prince, are seven weeks, and sixty-two weeks. The street and the moat shall be built again, even in troublous times.
