1060. Verse 18 And Noah's sons who went out of the ark were Shem, Ham, and Japheth. And Ham was the father of Canaan.

'Noah's sons who went out of the ark' means those who constituted the Ancient Church, 'who went out of the ark' meaning those who had been regenerated. 'Shem' means the internal Church, 'Ham' the corrupted Church, 'Japheth' the external Church. 'Ham was the father of Canaan means that from the corrupted Church arose worship in external things devoid of internal, which worship is meant by Canaan.
