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.

8274. 'Jehovah is His name' means that He alone is the Source of all things. This is clear from the meaning of Jehovah's 'name' as all aspects of faith and love or all aspects of truth and good in their entirety through which the Lord is worshipped, dealt with in 2724, 3006, 6674, and in the highest sense as the Lord's Divine Human, 2628, 6887, the Source of all those aspects. From this and also from the consideration that Jehovah is Being (Esse) itself, and so is the being within all things, it is evident that Jehovah is His name' means that the Lord alone is the Source of all things.
