'Earth' in the Bible

For they are wilfully blind to the fact that there were heavens which existed of old, and an earth, the latter arising out of water and extending continuously through water, by the command of God;

But the present heavens and the present earth are, by the command of the same God, kept stored up, reserved for fire in preparation for a day of judgement and of destruction for the ungodly.

The day of the Lord will come like a thief--it will be a day on which the heavens will pass away with a rushing noise, the elements be destroyed in the fierce heat, and the earth and all the works of man be utterly burnt up.

But in accordance with His promise we are expecting new heavens and a new earth, in which righteousness will dwell.
