'Seven' in the Bible

Then was Nebuchadnezzar full of fury, and the form of his appearance was changed against Shadrach, Meshach, and Abednego: [therefore] he spoke, and commanded that they should heat the furnace seven times more than it was usually heated.

Whereas the king saw a watcher and a holy one coming down from the sky, and saying, Cut down the tree, 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 wet with the dew of the sky: and let his portion be with the animals of the field, until seven times pass over him;

that you shall be driven from men, and your dwelling shall be with the animals of the field, and you shall be made to eat grass as oxen, and shall be wet with the dew of the sky, and seven times shall pass over you; until you know that the Most High rules in the kingdom of men, and gives it to whomever he will.

and you shall be driven from men; and your dwelling shall be with the animals of the field; you shall be made to eat grass as oxen; and seven times shall pass over you; until you know that the Most High rules in the kingdom of men, and gives it to whomever he will.

Know therefore and discern, that from the going forth of the commandment to restore and to build Jerusalem to the Anointed One, the prince, shall be seven weeks, and sixty-two weeks: it shall be built again, with street and moat, even in troubled times.
