'Of The Earth' in the Bible

"Ye are the salt of the earth: but and if the salt have lost her saltiness, what can be salted therewith? It is thenceforth good for nothing, but to be cast out, and to be trodden underfoot of men.

For as Jonah was three days and three nights in the whale's belly; so shall the son of man be three days and three nights in the heart of the earth.

He said, "Yea." And when he was come into the house, Jesus spake first to him, saying, "What thinkest thou Simon? Of whom do the kings of the earth take tribute, or poll money? Of their children, or of strangers?"

And then shall appear the sign of the son of man in heaven. And then shall all the kindreds of the earth mourn, and they shall see the son of man come in the clouds of heaven with power and great glory.
