'Seven' in the Bible

Then was Nebuchadnezzar full of fury, and the form of his visage was changed against Shadrach, Meshach, and Abed-nego: therefore he spake, 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 heaven, and saying, Hew down the tree, and destroy it; nevertheless leave the stump of the roots thereof in the earth, even with a band of iron and brass, in the tender grass of the field, and let it be wet with the dew of heaven: and let his portion be with the beasts of the field, till seven times pass over him;

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

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

Know therefore and discern, that from the going forth of the commandment to restore and to build Jerusalem unto the anointed one, the prince, shall be seven weeks, and threescore and two weeks: it shall be built again, with street and moat, even in troublous times.
