'Whereof' in the Bible

There is a river, the streams whereof shall make glad the city of God, the holy place of the tabernacles of the most High.

They have prepared a net for my steps; my soul is bowed down: they have digged a pit before me, into the midst whereof they are fallen themselves. Selah.

Turn away my reproach whereof I am afraid; For thine ordinances are good.

The LORD hath done great things for us; whereof we are glad.
