Earth

In both Hebrew and Greek the same word is used to denote the earth as a whole, and a particular land. Only the context can enable us to decide in which of these senses it is to be taken in a given passage.

Thus in Matthew 27:45 we might, so far as the original word is concerned, render either "there was darkness over all the land," or over all the earth. The expression "all the earth" is sometimes used hyperbolically for a large portion of it, Ezra 1:2. The word is used of the whole world, etc. In a moral sense, earthly is opposed to what is heavenly, spiritual and holy, John 3:31 1 Corinthians 15:47 Colossians 3:2 James 3:15. "The lower parts of the earth," means the unseen world of the dead, Psalms 63:9 Isaiah 44:23 Ephesians 4:9.

EARTH, n. erth.

1. Earth, in its primary sense, signifies the particles which compose the mass of the globe, but more particularly the particles which form the fine mold on the surface of the globe; or it denotes any indefinite mass or portion of that matter. We throw up earth with a spade or plow; we fill a pit or ditch with earth; we form a rampart with earth. This substance being considered, by ancient philosophers, as simple, was called an element; and in popular language, we still hear of the four elements, fire, air,earth, and water.
2. In chimistry, the term earth was, till lately, employed to denote a simple elementary body or substance, tasteless, inodorous, uninflammable and infusible. But it has also been applied to substances which have a very sensible alkaline taste, as lime. The primitive earths are reckoned ten in number, viz, silex, alumin, lime, magnesia, baryte, strontian, zircon, glucin, yttria and thorina. Recent experiments prove that most or all of them are compounds of oxygen with bases, some of which appear to possess the properties of metals. In this case the earths are to be considered as metallic oxyds.
3. The terraqueous globe which we inhabit. The earth is nearly spherical, but a little flatted at the poles, and hence its figure is called an oblate spheroid. It is one of the primary planets, revolving round the sun in an orbit which is between those of Venus and Mars. It is nearly eight thousand miles in diameter, and twenty five thousand miles in circumference. Its distance from the sun is about ninety five millions of miles,and its annual revolution constitutes the year of 365 days, 5 hours, and nearly 49 minutes.
4. The world, as opposed to other scenes of existence.
5. The inhabitants of the globe.

The whole earth was of one language. Gen.11.

6. Dry land, opposed to the sea.

God called the dry land earth. Gen.1.

7. Country; region; a distinct part of the globe.

In this sense, land or soil is more generally used.

In scripture, earth is used for a part of the world. Ezra. 1.2.

8. The ground; the surface of the earth. He fell to the earth. The ark was lifted above the earth.

In the second month--was the earth dried. Gen.8.

9. In scripture, things on the earth, are carnal, sensual, temporary things; opposed to heavenly, spiritual or divine things.
10. Figuratively, a low condition. Rev.12.
11. from ear, L. aro, to plow. The act of turning up the ground in tillage. Not used.

EARTH, v.t. To hide in the earth.

The fox is earthed.

1. To cover with earth or mold.

EARTH, v.i. To retire under ground; to burrow. Here foxes earthed.

Earth

The term is used in two widely-different senses: (1) for the material of which the earth’s surface is composed; (2) as the name of the planet on which man dwells. The Hebrew language discriminates between these two by the use of separate terms, adamah for the former, erets for the latter. Adamah is the earth in the sense of soil or ground, particularly as being susceptible of cultivation. (Genesis 2:7) Erets is applied in a more or less extended sense-- (1) to the whole world, (Genesis 1:1) (2) to land as opposed to sea, (Genesis 1:10) (3) to a country, (Genesis 21:32) (4) to a plot of ground, (Genesis 23:15) and (5) to the ground on which a man stands. (Genesis 33:3) The two former senses alone concern us, the fairest involving an inquiry into the opinions of the Hebrews on cosmogony, the second on geography. cosmogony. -- (1) The Hebrew cosmogony is based upon the leading principle that the universe exists, not independently of God, nor yet co-existent with God, nor yet in opposition to him as a hostile element, but dependently upon him, subsequently to him and in subjection to him. (2) Creation was regarded as a progressive work --a gradual development from the inferior to the superior orders of things. Geography. --There seems to be traces of the same ideas as prevailed among the Greeks, that the world was a disk, (Isaiah 40:22) bordered by the ocean, with Jerusalem as its centre, like Delphi as the navel, or, according to another view, the highest point of the world. As to the size of the earth, the Hebrews had but a very indefinite notion.
