'In Those Days' in the Bible

Thus saith the Lord GOD; Art thou he of whom I have spoken in old time by my servants the prophets of Israel, which prophesied in those days many years that I would bring thee against them?

And it will come about in those days, that I will give to Gog a last resting-place there in Israel, in the valley of Abarim on the east of the sea: and those who go through will be stopped: and there Gog and all his people will be put to rest, and the place will be named, The valley of Hamon-gog.
