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.

732. Verse 5 And Noah did according to all that Jehovah commanded him means, as previously, that it was so accomplished.

See the previous chapter, at 6:22, where it is said twice of Noah that he 'did', whereas in this verse it is said only once. In that verse the name 'God' is used, but in this 'Jehovah'. The reason is that the previous chapter deals with things of the understanding, the present with those of the will. Things of the understanding view those of the will as things different and separate from themselves, but those of the will view those of the understanding as things united to themselves or as a unity, for the understanding has its being from the will. This is why the verb 'to do' is used twice in 6:22 but only once at this point, and also why the name 'God' is used there but 'Jehovah' here.
