'Whereof' in the Bible

And now therefore thus saith the LORD, the God of Israel, concerning this city, whereof ye say, It shall be delivered into the hand of the king of Babylon by the sword, and by the famine, and by the pestilence;

And fields shall be bought in this land, whereof ye say, It is desolate without man or beast; it is given into the hand of the Chaldeans.

Then it shall come to pass, that the sword, which ye feared, shall overtake you there in the land of Egypt, and the famine, whereof ye were afraid, shall follow close after you there in Egypt; and there ye shall die.
