Arcana Coelestia # 7727
7727. 'And we must make them to Jehovah our God' means which - namely worship - is acceptable to the Lord. This is clear from what comes before; that is to say, 'sacrifices and burnt offerings' means worship, 7726, and 'flocks and herds', from which the sacrifices were taken, means the good from which the offering of worship is made, 7723, 7724, so that 'making sacrifices and burnt offerings to Jehovah' means an offering of worship from good which is acceptable - 'Jehovah' in the Word being the Lord, see 1343, 1736, 2921, 3023, 3035, 5041, 5663, 6280, 6281, 6307, 6905, 6945, 6956.
Arcana Coelestia # 1342
1342. Verse 14 And Shelah lived thirty years, and he begot Eber.
'Shelah lived thirty years' means the beginning of the third state, 'Shelah' here, as previously, meaning that which is the offspring of knowledge. 'And he begot Eber' means a derivative from this, 'Eber' being a nation, the Hebrew nation, which took its name from Eber as its forefather, and which means the worship in general of the second Ancient Church.
