'Whereof' in the Bible

And now therefore Jehovah, the God of Israel, saith thus concerning this city, whereof ye say, It hath been given over 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 fear shall overtake you there in the land of Egypt, and the famine, whereof ye are afraid, shall follow hard after you there in Egypt; and there ye shall die.

The earth quaketh at the sound of their fall; there is a cry, the sound whereof is heard in the Red sea.
