H
The letter H involves infinity, because it is only an aspirate. That is why it was added to the names of Abram and Sarai, that each might represent the divine, or Jehovah.
The Hebrew letter "ה" pronounced Hay, begins Psalm 119:33-40. Added to the names Abram and Sarai, it signifies the Infinite and Eternal. (True Christian Religion 272; Doctrine Regarding Sacred Scripture 90)
As Abram represents the Lord, his former quality was to be destroyed; and so the letter H was taken from the name Jehovah, for it is the only one there which involves what is divine, and means I Am, or Esse -- to be; and then he was called Abraham, and Sarai became Sarah. (Arcana Coelestia 2010)

Apocalypse Explained #38
38. And they who pierced Him, signifies that they also will see Him who are in falsities from evil. This is evident from the signification of "piercing," as being those who altogether deny the Lord, for these kill and pierce Him in themselves; for these are meant by the soldier who pierced His side (John 19:34-37). By "soldier" and "soldiers" are meant those who are of the church, and who should fight for the Lord. Here in particular are meant those of the Jewish church, and, in general, all that are of the church who are in falsities from evil. And as such were signified by "soldiers," the soldiers divided the Lord's garments, and cast lots upon His coat; which means that the Jewish church dispersed the Divine truths that are in the sense of the letter of the Word, but were unable to disperse interior truths, or the truths of the internal sense (for "garments" signify truths in ultimates; see Arcana Coelestia, n. 5248, 6918, 9158, 9212; "to divide" signifies to dissipate and disperse, see n. 4424, 6360, 6361, 9093; and "the coat" interior truths, n. 9048, 9212, 9216, 9826).
