Thou hast heard, see all this; as thou hast heard all these things from my mouth, from time to time, so now I advise thee to see, i.e. seriously to consider them, and to lay them to heart. Will not ye declare it? I call you to witness; must you not be forced to acknowledge the truth of what I say? Deny it if you can. Or, have ye not declared it unto all people, as occasion required it? Have you not boasted unto the Gentiles of this as your honour and privilege? I have showed thee new things from this time; and I have now given thee new predictions of secret things, and such as till this time were wholly unknown to thee, as it follows, concerning thy deliverance out of Babylon by Cyrus.
