It must also be remembered, that there are words in the New Testament which are not found at all in the classical writers. When new ideas are to be conveyed, new words must be found to convey them. In the language of the Hindus there is no word for home, simply because the Hindu has no home. The idea of a home as understood by Christians, is utterly foreign to the Hindu nation and religion. There are heathen nations that have no word for gratitude, because gratitude is unknown to them; so the word agape or charity, which describes unselfish love, a love which reaches to enemies, and which seeks no personal gratification or reward,—that love which is of God, and concerning which it is said, "God is Love," refers to something unknown to the heathen world. They had no word to express it, because they had not the thing itself to express. These illustrations indicate some of the peculiarities of the New Testament Greek, and serve to show use why the student of the Bible needs an especial apparatus for studying the Greek New Testament. For this purpose, he has been most generously furnished with New Testament lexicons, in different languages, Latin, German, and English, by the labor of devout and learned students. Among the most noteworthy may be mentioned Robinson's Greek Lexicon of the New Testament, and Prof. J. H. Thayer's later and more elaborate Greek-English Lexicon of the New Testament, based upon Prof. Grimm's get Lexicon; which is well adapted to meet the needs of the critical student. The meaning of words is determined finally by their usage by those who employ them, and the only way to settle the sense of disputed and difficult words is carefully to examine each word in its connection, in all the passages where it is used, and in the light of that examination decide as to its meaning or meanings. In some of the more elaborate lexicons a large number of passages are thus cited, illustrating the use of the words under consideration, and it some cases authors have endeavored to give nearly every passage where a word occurs in the New Testament. This however, cumbers the lexicon with a large amount of material which in most instances is of little use. This examination and comparison of passages, the careful student should make for himself, and his interests in this direction are better served by the use of a concordance; and for those who wish to investigate carefully the meaning of Greek words in the New Testament, ample provision has been made in the Critical Greek and English Concordance, prepared by Prof. C. F. Hudson, under the direction of H. L. Hastings, and revised and completed by the late Ezra Abbot, D.D., LL.D., Profession of New Testament Criticism and Interpretation in the Divinity School of Harvard University.
