Anf-03 iv.ix.iv Pg 9 Thus, therefore, before this temporal sabbath, there was withal an eternal sabbath foreshown and foretold; just as before the carnal circumcision there was withal a spiritual circumcision foreshown. In short, let them teach us, as we have already premised, that Adam observed the sabbath; or that Abel, when offering to God a holy victim, pleased Him by a religious reverence for the sabbath; or that Enoch, when translated, had been a keeper of the sabbath; or that Noah the ark-builder observed, on account of the deluge, an immense sabbath; or that Abraham, in observance of the sabbath, offered Isaac his son; or that Melchizedek in his priesthood received the law of the sabbath.
I am not acquainted with any such passage. Oehler refers to Isa. xlix. in his margin, but gives no verse, and omits to notice this passage of the present treatise in his index.
