'Ground' in the Bible

But this they said proving him, that they might have something to accuse him of. But Jesus, having stooped down, wrote with his finger on the ground.

And again stooping down he wrote on the ground.

Having said these things, he spat on the ground and made mud of the spittle, and put the mud, as ointment, on his eyes.

Verily, verily, I say unto you, Except the grain of wheat falling into the ground die, it abides alone; but if it die, it bears much fruit.

When therefore he said to them, I am he, they went away backward and fell to the ground.
