P1599:13, 142:3.21
"And then, amidst the thunders and lightnings of Sinai, Moses gave them the
new ten commandments, which you will all allow
are more worthy utterances to accompany the enlarging Yahweh concepts of Deity.
And did you never take notice of these commandments as twice recorded in the
Scriptures, that in the first case deliverance from Egypt is assigned as the
reason for Sabbath keeping, while in a later record the advancing religious
beliefs of our forefathers demanded that this be changed to the recognition
of the fact of creation as the reason for Sabbath observance?
