Oecumenius : "in the day when I took them by the hand to lead them out of the land of Egypt." So that they do not suppose that the exodus is according to the covenant with Abraham; for it has occurred in Christ, "For to your seed," he says, "who is Christ;" (Gal. 3:16) it brings forth what kind of covenant the exodus has become. That of the Exodus, he says, made through Moses. For to say, "not according to that covenant," he shows it to be cast away, as if he were saying, "I will give another covenant, not such as I have already given. For that one, because of its weakness, has been cast away from me." "because they did not continue." As if the statement serves as a defense for God's negligence; for He says, they did not continue My covenant. For from them began the disobedience, and thus God's negligence followed. — The Pseudo-Oecumenian Catena on Hebrews
