415. And I looked, and I heard an angel flying in the midst of heaven. (8:13) This symbolizes instruction and prediction from the Lord.

In the highest sense an angel means the Lord, and so also something from the Lord (no. 344). And to fly in the midst of heaven and speak means, symbolically, to perceive and understand, and when said of the Lord, to foresee and provide (no. 245). But here it means to instruct and predict.

8867. 'You shall not have other gods before My face' means that there must be no thought about truths from any source other than the Lord. This is clear from the meaning of 'gods' as truths, and in the contrary sense as falsities, dealt with in 4402, 4544, 7268, 7873, 8301; and from the meaning of 'face', in a reference to God's face, as love, mercy, peace, and goodness, dealt with in 222, 223, 4311, 5585, thus the Lord Himself, since the Lord is the Source from which these spring. The reason why 'there must be no other gods before My face' means that there must be no thought about truths from any source other than the Lord is also that the Lord's Divine Human, meant by 'I am Jehovah your God', is mentioned first, which is therefore first in line and must reign universally in each individual truth that follows, 8864, 8865. Consequently the commandment now declares such things as are to be avoided because they are thoroughly destructive and prevent the Lord from reigning universally in each and every truth contained in the commandments and statutes that were dictated and commanded from Mount Sinai. The first thing that would be destructive is thought about truths from a source other than the Lord, which is meant in the words that prohibit the presence of other gods before the Lord's face. All other things which would destroy that truth reigning universally are contained in the prohibitions that follow in sequence - that they were not to make a graven image for themselves; that they were not to make any likeness of the things that were in the heavens, on the earth, and in the waters and that they were not to bow down to them, and not to serve them. And after these therefore comes the reiteration 'for I am Jehovah your God', meaning that the Lord must be in every single one.
