Seven
Seven, as in Revelation 15:1, signifies everything in an universal sense. The number 'seven' was considered holy, as is well known, because of the six days of creation, and the seventh, which is the celestial self, where peace, rest, and the Sabbath is. The number seven occurs so frequently in the rites of the Jewish church and is held holy everywhere.
So times were divided into seven, longer and shorter intervals, and were called weeks, like the great intervals of times till the coming of the Messiah, in Daniel 9:24-25. The time of seven years is called 'a week' by Laban and Jacob, as in Genesis 29:27-28. So wherever the number seven occurs, it is considered holy and sacred, as in Psalm 119:164, and in Isaiah 30:26.
As the periods of a person's regeneration are distinguished into six, prior to the seventh, or the celestial self, so the times of vastation are also distinguished, until nothing celestial is left. This was represented by the many captivities of the Jews, and by the last Babylonian captivity, which lasted seven decades, or seventy years. This was also represented by Nebuchadnezzar, in Daniel 4:16, 22, 29. It also refers to the vastation of the end times, in Revelation 15:1, 7-8. They should 'tread the holy city under foot, forty and two months, or six times seven,' as in Revelation 11:2 and Revelation 5:1. So the severity and increments of punishment were expressed by the number seven, as in Leviticus 26:18, 21, 24, 28 and Psalm 79:12.

Isaiah 31
1
Woe to those who go down to Egypt for help, and rely on horses, and trust in chariots because they are many, and in horsemen because they are very strong, but they don't look to the Holy One of Israel, and they don't seek Yahweh!
2
Yet he also is wise, and will bring disaster, and will not call back his words, but will arise against the house of the evildoers, and against the help of those who work iniquity.
3
Now the Egyptians are men, and not God; and their horses flesh, and not spirit. When Yahweh stretches out his hand, both he who helps shall stumble, and he who is helped shall fall, and they all shall be consumed together.
4
For thus says Yahweh to me, "As the lion and the young lion growling over his prey, if a multitude of shepherds is called together against him, will not be dismayed at their voice, nor abase himself for the noise of them, so Yahweh of Armies will come down to fight on Mount Zion and on its heights.
5
As birds hovering, so Yahweh of Armies will protect Jerusalem. He will protect and deliver it. He will pass over and preserve it."
6
Return to him from whom you have deeply revolted, children of Israel.
7
For in that day everyone shall cast away his idols of silver and his idols of gold--sin which your own hands have made for you.
8
"The Assyrian will fall by the sword, not of man; and the sword, not of mankind, shall devour him. He will flee from the sword, and his young men will become subject to forced labor.
9
His rock will pass away by reason of terror, and his princes will be afraid of the banner," says Yahweh, whose fire is in Zion, and his furnace in Jerusalem.
