Easton's 1897 Bible Dictionary:

Everlasting
   eternal, applied to God (Gen. 21:33; Deut. 33:27; Ps. 41:13;
   90:2). We also read of the "everlasting hills" (Gen. 49:26); an
   "everlasting priesthood" (Ex. 40:15; Num. 25:13). (See ETERNAL.)


The Devil's Dictionary (1881-1906):

EVERLASTING, adj.  Lasting forever.  It is with no small diffidence
that I venture to offer this brief and elementary definition, for I am
not unaware of the existence of a bulky volume by a sometime Bishop of
Worcester, entitled, _A Partial Definition of the Word "Everlasting,"
as Used in the Authorized Version of the Holy Scriptures_.  His book
was once esteemed of great authority in the Anglican Church, and is
still, I understand, studied with pleasure to the mind and profit of
the soul.
