Arcana Coelestia #9194
9194. 'Except to Jehovah alone' means that the Lord, who is the one and only God, is to be worshipped. This is clear from the meaning of 'offering sacrifice', at this point 'to Jehovah alone', as worship, dealt with above in 9192. The reason why 'to Jehovah' means to the Lord is that in the Word 'Jehovah' is used to mean no one other than the Lord, see 1343, 1736, 2921, 3023, 3035, 4692, 5663, 6303, 6905, 8864. The Divine, which He called the Father, is the Divine Good within Himself, 2803, 3704, 7499, 8897. Thus the Lord is the one and only God, 1607, 2149, 2156, 2329, 2447, 2751, 3194, 3704, 3712, 3938, 4577, 4687, 5321, 6280, 6371, 6849, 6993, 7014, 7182, 7209, 8241, 8724, 8760, 8864, 8865.

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.
