Characters in the Bible will often address others using the term “my lord,” and it seems to be no more than an expression of respect. The name “the Lord” refers to the Divine Good, and that when the term “lord” is applied to men or angels it also refers to the desire to be good.

2201. Verse 12 And Sarah laughed within herself, saying, After I have grown old, shall I have this pleasure, and my lord being old?

'Sarah laughed within herself' means the affection possessed by that rational truth that such was to take place. 'Saying, After I have grown old, shall I have this pleasure?' means that the affection possessed by that truth had no inclination to change its state. 'And my lord being old' means that the affection for truth was amazed that rational good to which truth was allied was also to cast off the human.
