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.

93. Weil der Maria vom Engel Gabriel gesagt wurde „Das Heilige, das von dir geboren wird, wird Sohn Gottes genannt werden.“, so sollen im Folgenden Stellen aus dem göttlichen Wort angeführt werden, in denen der Herr seiner Menschennatur nach der „Heilige Israels“ genannt wird:

„Ich schaute in Gesichten … und siehe, ein Wächter und ein Heiliger stieg aus dem Himmel herab.“ (Daniel 4:10, 20) „Gott wird aus Theman kommen, und der Heilige vom Berge Paran.“ (Habakuk 3:3) „Ich bin Jehovah, dein Gott, der Heilige Israels … euer Heiliger, der Israel erschaffen.“ (Jesaja 43:3, 11, 14-15) „So spricht Jehovah, der Erlöser Israels, sein Heiliger.“ (Jesaja 49:7) „So spricht Jehovah, dein Gott, der Heilige Israels, sein Heiland.“ (Jesaja 43:1, 3) „Unser Erlöser, Jehovah der Heerscharen ist sein Name, der Heilige Israels.“ (Jesaja 47:4) „So spricht Jehovah, euer Erlöser, der Heilige Israels.“ (Jesaja 43:14; 48:17) „Jehovah der Heerscharen ist sein Name, und dein Erlöser, der Heilige Israels.“ (Jesaja 54:5)4.
