10154. 'And I will be their God' means the Lord's presence and His influx into truth in the Church. This is clear from the meaning of 'being their God' as the Lord's presence and His influx into truth - into truth because in the Old Testament Word the Lord is called God where truth is the subject, but Jehovah where good is the subject. This also goes to explain why angels are called gods, because they are recipients of Divine Truth from the Lord, and in addition why in the original language the plural word Elohim is used to denote God; for truths are many but good is one, Matthew 19:16-17.

The Lord is called God where truth is the subject but Jehovah where good is the subject, see 2586, 2769, 2807, 2822, 3921, 4287, 4402, 7010, 9167.

Angels are called gods, because they are recipients of Divine Truth from the Lord, 4295, 4402, 7268, 7873, 8192, 8302, 8867, 8941.

In the Word Jehovah means the Lord, see the places referred to in 9373; and in Isaiah He is called explicitly 'Father from eternity' and also 'God',

To us a Boy is born, to us a Son is given, and the government will be upon His shoulder; His name is called, God, Hero, Father of Eternity, Prince of peace. Isaiah 9:6.

And in the same prophet,

A virgin will conceive and bear [a son], and His name will be called Immanuel, that is, God with us. Isaiah 7:14; Matthew 1:23.

The meaning of the words here 'I will be their God' as the Lord's presence and His influx into truth is also evident from the fact that 'I will dwell in the midst of the children of Israel' means the Lord's presence and His influx through good. For wherever good is the subject in the Word, so too is truth, on account of the heavenly marriage, which is that of goodness and truth, in every single part of the Word, see the places referred to in 9263, 9314.

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.
