715. Since the most ancient people knew and when in self-abasement acknowledged that they were nothing but beasts and wild animals, and that the Lord alone enabled them to be human beings, they not only used to liken whatever resided with themselves to beasts and birds but also called them such. Things of the will they compared to beasts and called them beasts, and those of the understanding they compared to birds and called them birds. They differentiated however between good affections and evil affections. Good affections they compared to lambs, sheep, kids, he-goats, young she-goats, rams, young bulls, and oxen, because they were good and gentle creatures, and also because they had a use in life in that they could be eaten and men could clothe themselves with their skins and wool. These are chiefly the clean beasts. But the evil and savage ones, which also have no use in life, are unclean beasts.

84. Verses 2-3 And on the seventh day God finished His work which He had made, and rested on the seventh day from all His work which He had made. And God blessed the seventh day and made it holy, for on that day He rested from all His work which God had created when making it.

The celestial man is 'the seventh day'; and because throughout the six days it has been the Lord at work, that man is called 'His work'. In addition, because conflict at that point ceases, the Lord is said 'to rest from all His work'. It was for this reason that the seventh day was made holy and was called the Sabbath from a word for 'rest'; and it was in this manner that man was created, formed, and made, as may be seen plainly from the words themselves.
