'Earth' in the Bible

He who comes from above is above all. He whose origin is from the earth is not only himself from the earth, his teaching also is from the earth. He who comes from Heaven is above all.

For I have left Heaven and have come down to earth not to seek my own pleasure, but to do the will of Him who sent me.

And I-- if I am lifted up from the earth--will draw all men to me."

I have glorified Thee on earth, having done perfectly the work which by Thine appointment has been mine to do.
