7245. 'behold, I am uncircumcised in the lips' means that it is impure, that is to say, the law of God is impure to those who are steeped in falsities.

AC 7245a. 'And how will Pharaoh hear me?' means that for that reason those steeped in falsities are not going to accept it. This is clear from what was stated above in 7224, 7225, where the same words occur. When Moses says that he is 'uncircumcised in the lips' the meaning in the internal sense, according to what has been shown in 7225, is that the law of God is seen to be impure by those steeped in falsities. In the historical sense however, in which Moses as the head stands for the descendants of Jacob and whatever there is of the Church among them, as shown above in 7041, 'uncircumcised in the lips' means that Divine worship among that nation was of such a nature. For the worship among that nation was impure, since they venerated outward things and totally rejected inner values, which are faith and charity. Indeed they spurned any actual recognition of inner realities, such as all those which religious observances served to mean and represent. And because that nation was like this their worship was impure; for they were led to worship Jehovah by self-love and love of the world, not by love to Him and love towards the neighbour. This impure worship is meant in the historical sense when Moses says that he is 'uncircumcised in the lips'; but the meaning in the internal sense is as explained above in 7225.
