But when thou shalt have passed the Red Sea, when thou shalt have been led forth out of thine offences “with a mighty hand and with a strong arm,” thou wilt perceive mysteries that thou knowest not: since Joseph himself too, “when he came out of the land of Egypt, heard a language which he knew not.” Thou shalt hear a language which thou knowest not: which they that know now hear and recognise, bearing witness and knowing. Thou shalt hear where thou oughtest to have thy heart: which just now when I said many understood and answered by acclamation, the rest stood mute, because they have not heard the language which they knew not. Let them hasten, then, let them pass over, let them learn.
