In Ezekiel 16:7, the breast signifies natural good.

(Riferimenti: Arcana Coelestia 3301)

In Exodus 29:26, this signifies the divine spiritual in the heavens and its appropriation there. It also signifies the good of charity. (Arcana Coelestia 10087)

10087. 'And you shall take the breast' means the Divine Spiritual in the heavens, which those in heaven make their own. This is clear from the meaning of 'the breast' as the good of charity, and in the highest sense as the Divine Spiritual, dealt with below. The reason why its being made their own by those in the heavens is meant is that the subject in what follows next is the flesh from the ram and the bread from the basket which were not burned on the altar but were left as a portion for and were eaten by Moses, Aaron, and his sons. By this is meant making it their own, the process of which is described in what follows next. The origin of the meaning of 'the breast' as the good of charity, and in the highest sense as the Divine Spiritual, lies in correspondence. For the human head corresponds to the good of love to the Lord, which is the good of the inmost heaven and is called the Divine Celestial, whereas the breast corresponds to the good of charity, which is the good of the middle or second heaven and is called the Divine Spiritual; and the feet correspond to the good of faith, thus to the good of obedience, which is the good of the lowest heaven and is called the Divine Natural. Regarding this correspondence, see what has been shown above in 10030.

[2] Since the breast because of its correspondence means the good of charity, and the good of charity results from the will to do good, John - who represented that good - leaned on the Lord's breast or in His bosom, John 13:23, 25, by which the Lord's love of that good is meant. For 'leaning on the breast' or 'in the bosom' means loving. Anyone who knows this may also know what the meaning is of the following words which the Lord addressed to Peter and to John,

Jesus said to Simon Peter, Simon son of Jonah, do you love Me? He said, Yes, Lord, You know that I love You. He said to him, Feed My lambs. He said to him again, Simon son of Jonah, do you love Me? He said, Yes, Lord, You know that I love You. He said to him, Feed My sheep. He said to him a third time, Simon son of Jonah, do you love Me? Peter was grieved, therefore he said, Lord, You know all things; You know that I love You. Jesus said to him, Feed My sheep. Truly I say to you, When you were younger you girded yourself and walked where you wished; but when you are old you will stretch out your hands and another will gird you and lead you where you do not wish. When He had said this He said to him, Follow Me. Having turned round Peter saw the disciple whom Jesus loved following, who also had leaned on His breast at the supper. Seeing him Peter said, Lord, what about him? Jesus said to him, If I will that he remain until I come, what is that to you? You follow Me. John 21:15-22.

None can know what these words mean except through the internal sense. This teaches that the Lord's twelve disciples represented all aspects of faith and love in their entirety, just as the twelves tribes of Israel did, and that Peter represented faith, James charity, and John the works or good deeds that flow from charity.

The Lord's twelve disciples represented all aspects of faith and love in their entirety, see 3488, 3858 (end), 6397.

The twelve tribes of Israel had the same representation, 3858, 3926, 4060, 6335, 6640.

Peter represented faith, James charity, and John the works that flow from charity, Prefaces to Genesis 18, 22, and 3750, 4738, 6344 (end).

'The rock', as Peter is also called, means the Lord in respect of faith, 8581.

[3] Faith without charity does not love the Lord; nevertheless it is able to teach about things connected with faith and love, and the things that are the Lord's. This was why the Lord said three times, 'Do you love Me?', and then, 'Feed My lambs' or 'Feed My sheep'. For the same reason He says, 'When you were younger you girded yourself and walked where you wished; but when you are old you will stretch out your hands and another will gird you and lead you where you do not wish', meaning that in its early stages the Church's faith had possessed the good of innocence, like a young child; but when it was in decline, which is the final phase of the Church, faith would not possess that good any longer nor the good of charity, at which point evil and falsity would lead it. All this is what is meant by 'when you are old you will stretch out your hands and another will gird you and lead you where you do not wish', that is, you will pass from freedom into bondage. 'Girding' means being acquainted with and seeing truths in light that flows from good, 9952, and 'walking' leading a life in accord with those truths, 8417, 8420, so that 'girding himself and walking where he wished' means acting in freedom; and people act in freedom when an affection for truth springing from good governs their actions, 2870-2893, 9585-9591, and they are led by the Lord, 9096, 9586, 9589-9591. But 'being girded by another and being led where he did not wish' means being in bondage, and people are in bondage when evil governs their actions, and so they are led by hell, 9096, 9586, 9589-9591. 'Lambs', which the Lord mentions first, are those in whom the good of innocence is present, see 3994; 'sheep', which the Lord mentions the second and third times, are those in whom the good of charity, and faith springing from this, are present, 4169, 4809. Also three means the whole period from beginning to end, 2788, 4495, 7715, 9198; consequently, since the Lord spoke to Peter regarding the Church from its early stages to when it was in decline, He said three times, Do you love Me?

[4] As regards John's following the Lord, this was a sign of the truth that those who perform the good deeds of charity follow the Lord, are loved by the Lord, and do not leave Him, whereas those whose faith is separated from charity not only fail to follow the Lord but are also angered by that truth, as Peter was then; not to mention many more arcana within the words contained in that passage.

From all this it is evident also that leaning on the Lord's breast or in His bosom means being loved by Him, and that this expression is used in reference to those who perform the good deeds of charity. Much the same is meant by carrying in the bosom, Isaiah 40:10-11, and lying in the bosom, 2 Samuel 12:3.
