Which is totally against what the Word says. God made an unconditional and everlasting covenant with Abraham. The Jews lost use of the land through disobedience, but never the deed. Everlasting means what it says.
You are right, the word "everlasting" means what it says,
which is determined by the context.
From the Theological Wordbook of the Old Testament on the Hebrew word
olam -
1631a עוֹלָם (‘ôlām) forever, ever, everlasting, evermore, perpetual, old, ancient, world, etc. (RSV similar in general, but substitutes “always” for “in the world” in Ps 73:12 and “eternity” for “world” in Ecc 3:11.) Probably derived from ‘ālam I, “to hide,” thus pointing to what is hidden in the distant future or in the distant past. The Ugaritic cognate is ‘lm, “eternity.”
Though ‘ôlām is used more than three hundred times to indicate indefinite continuance into the very distant future, the meaning of the word is not confined to the future. There are at least twenty instances where it clearly refers to the past. Such usages generally point to something that seems long ago, but rarely if ever refer to a limitless past. Thus in Deut 32:7 and Job 22:15 it may refer to the time of one’s elders. In Prov 22:28; 23:10; Jer 6:16; 18:15; 28:8 it points back somewhat farther. In Isa 58:12, 61:4; Mic 7:14; Mal 3:4, and in the Aramaic of Ezr 4:15, 19 it clearly refers to the time just before the exile. In I Sam 27:8, in Isa 51:9 and 63:9, 11 and perhaps Ezk 36:2, it refers to the events of the exodus from Egypt. In Gen 6:4 it points to the time shortly before the flood. None of these past references has in it the idea of endlessness or limitlessness, but each points to a time long before the immediate knowledge of those living. In Isa 64:3 the KJV translates the word “beginning of the world.” In Ps 73:12 and Eccl 3:11 it is translated “world,” suggesting the beginning of a usage that developed greatly in postbiblical times.
Jenni holds that its basic meaning “most distant times” can refer to either the remote past or to the future or to both as due to the fact that it does not occur independently (as a subject or as an object) but only in connection with preposi-tions indicating direction (min “since,” ‘ad “until,” lĕ “up to”) or as an adverbial accusative of direction or finally as the modifying genitive in the construct relationship. In the latter instance ‘ōlām can express by itself the whole range of meanings denoted by all the prepositions “since, until, to the most distant time”; i.e. it assumes the meaning “(unlimited, incalculable) continuance, eternity.” (THAT II, p. 230) J. Barr (Biblical Words for Time (’1969), p. 73) says, “We might therefore best state the “basic meaning” as a kind of range between ‘remotest time’ and ‘perpetuity’”. But as shown above it is sometimes used of a not-so-remote past. For the meaning of the word in its attributive use we should note the designation of the lord as ’el ‘ōlām, “The Eternal God” (Gen 21:33).
The LXX generally translates ‘ōlām by aiōn which has essentially the same range of meaning.
That neither the Hebrew nor the Greek word in itself contains the idea of endlessness is shown both by the fact that they sometimes refer to events or conditions that occurred at a definite point in the past, and also by the fact that sometimes it is thought desirable to repeat the word, not merely saying “forever,” but “forever and ever.”
I underlined key point. This same word is used which is obviously not forever as dispensationalists claim it to be as in:
"Then his master shall bring him unto the judges; he shall also bring him to the door, or unto the door post; and his master shall bore his ear through with an aul; and he shall serve him for ever.(Heb
olam)" (Exod 21:6, KJV)
"This is my rest for ever(
olam): here will I dwell; for I have desired it." (Ps 132:14, KJV)
The 1828 Webster's definition:
EVERL`ASTING, a. [ever and lasting.] Lasting or enduring for ever; eternal; existing or continuing without end; immortal.
The everlasting God, or Jehovah. Gen 21.
Everlasting fire; everlasting punishment. Mat 18:25.
1. Perpetual; continuing indefinitely, or during the present state of things.
I will give thee, and thy seed after thee, the land of Canaan, for an everlasting possession. Gen 17.
The everlasting hills or mountains. Genesis. Habakkuk.
2. In popular usage, endless; continual; unintermitted; as, the family is disturbed with everlasting disputes.
The Israelites have not possessed the land for 2000 years, so that does away with everlasting or forever. The thought that Israel lost the use of the land by disobedience, but not the deed is man-made nonsense.
