Two
The number "two" has two different meanings in the Bible. In most cases "two" indicates a joining together or unification. This is easy to see if we consider the conflicts we tend to have between our "hearts" and our "heads" -- between what we want and what we know. Our "hearts" tell us that we want pie with ice cream for dinner; our "heads" tell us we should have grilled chicken and salad. If we can bring those two together and actually want what's good for us, we'll be pretty happy. We're built that way -- with our emotions balanced against our intellect -- because the Lord is built that way. His essence is love itself, or Divine Love, the source of all caring, emotion and energy. It is expressed as Divine Wisdom, which gives form to that love and puts it to work, and is the source of all knowledge and reasoning. In His case the two aspects are always in conjunction, always in harmony. It's easy also to see how that duality is reflected throughout creation: plants and animals, food and drink, silver and gold. Most importantly, it's reflected in the two genders, with women representing love and men representing wisdom. That's the underlying reason why conjunction in marriage is such a holy thing. So when "two" is used in the Bible to indicate some sort of pairing or unity, it means a joining together. In rare cases, however, "two" is used more purely as a number. In these cases it stands for a profane or unholy state that comes before a holy one. This is because "three" represents a state of holiness and completion (Jesus, for instance, rose from the tomb on the third day), and "two" represents the state just before it.
Jeremiah 25:1-12
1
The word that came to Jeremiah concerning all the people of Judah, in the fourth year of Jehoiakim the son of Josiah, king of Judah (the same was the first year of Nebuchadnezzar king of Babylon),
2
which Jeremiah the prophet spoke to all the people of Judah, and to all the inhabitants of Jerusalem, saying:
3
From the thirteenth year of Josiah the son of Amon, king of Judah, even to this day, these twenty-three years, the word of Yahweh has come to me, and I have spoken to you, rising up early and speaking; but you have not listened.
4
Yahweh has sent to you all his servants the prophets, rising up early and sending them (but you have not listened, nor inclined your ear to hear)
5
saying, Return now everyone from his evil way, and from the evil of your doings, and dwell in the land that Yahweh has given to you and to your fathers, from of old and even forevermore;
6
and don't go after other gods to serve them or worship them, and don't provoke me to anger with the work of your hands; and I will do you no harm.
7
Yet you have not listened to me, says Yahweh; that you may provoke me to anger with the work of your hands to your own hurt.
8
Therefore thus says Yahweh of Armies: Because you have not heard my words,
9
behold, I will send and take all the families of the north, says Yahweh, and [I will send] to Nebuchadnezzar the king of Babylon, my servant, and will bring them against this land, and against its inhabitants, and against all these nations around; and I will utterly destroy them, and make them an astonishment, and a hissing, and perpetual desolations.
10
Moreover I will take from them the voice of mirth and the voice of gladness, the voice of the bridegroom and the voice of the bride, the sound of the millstones, and the light of the lamp.
11
This whole land shall be a desolation, and an astonishment; and these nations shall serve the king of Babylon seventy years.
12
It shall happen, when seventy years are accomplished, that I will punish the king of Babylon, and that nation, says Yahweh, for their iniquity, and the land of the Chaldeans; and I will make it desolate forever.
