'Ground' in the Bible

Then fire went out from the presence of the Lord and consumed the burnt offering and the fat parts on the altar, and all the people saw it, so they shouted loudly and fell down with their faces to the ground.

for I am the Lord your God and you are to sanctify yourselves and be holy because I am holy. You must not defile yourselves by any of the swarming things that creep on the ground,

and take a censer full of coals of fire from the altar before the Lord and a full double handful of finely ground fragrant incense, and bring them inside the veil-canopy.

Therefore you must distinguish between the clean animal and the unclean, and between the unclean bird and the clean, and you must not make yourselves detestable by means of an animal or bird or anything that creeps on the ground -- creatures I have distinguished for you as unclean.
