Arcana Coelestia #9597
9597. 'With cherubs' means the Lord's watchfulness, guarding it from the approach of the hells and the harm they can do. This is clear from the meaning of 'cherubs' as watchfulness and providence, preventing any approach to the Lord except through good and protecting from harm the good from the Lord which exists in heaven and with man, dealt with in 9509, consequently guarding heaven from the approach of the hells and the harm they can do.
Revelation 14:19-20
19
The angel thrust his sickle into the earth, and gathered the vintage of the earth, and threw it into the great winepress of the wrath of God.
20
The winepress was trodden outside of the city, and blood came out from the winepress, even to the bridles of the horses, as far as one thousand six hundred stadia.
