54. We can see from the following passages that circumcision represented purification from evils that are caused by strictly earthly love:

Circumcise your heart and take away the foreskin of your heart, so that my wrath will not break forth because of the ill will of your deeds. (Jeremiah 4:4)

Circumcise the foreskin of your heart and no longer stiffen your neck. (Deuteronomy 10:16)

To circumcise the heart or the foreskin of the heart is to purify ourselves from evils.

Conversely, then, being uncircumcised or having a foreskin refers to people who have not been purified from evils caused by strictly earthly love and who are therefore not devoted to caring, and since having a foreskin means being unclean at heart, it says that no one who is uncircumcised at heart or uncircumcised in the flesh is to enter the sanctuary (Ezekiel 44:9); that no uncircumcised person is to eat the Passover meal (Exodus 12:48); and that the uncircumcised are damned (Ezekiel 28:10; 31:18; 32:19).

1067. Verse 20 And Noah began to be a man (vir) of the ground, and planted a vineyard.

'Noah began to be a man of the ground' means in general a person who has been instructed from matters of doctrine concerning faith. 'And he planted a vineyard' means the Church resulting from this, 'vineyard' being the spiritual Church.
