12
And he that is eight days old shall be circumcised among you, every male-child in your generations, he that is born in the house, or bought with money of any stranger, who is not of thy seed.
Genesis 17:12
Arcana Coelestia #2113
2113. Verse 27 And all the men of his house, he that was born in the house and he that was the purchase of silver, from the son who is a foreigner, were circumcised together with him.
'All the men of his house, he that was born in the house and he that was the purchase of silver' means all those at that time inside the Church. 'From the son who is a foreigner' means all who are rational outside the Church. 'Were circumcised by him' means that they were made righteous by the Lord.
