The fourth period extends from their return from the Babylonian Captivity to the present time, and to this belong some of the Prophets, the Chronicles, Ezra, Nehemiah, Esther, the final completion of the Psalms, the Septuagint translation of the Bible, the writings of Josephus, of Philo of Alexandria, and the rabbinical literature.

2. THE LANGUAGE.—The Hebrew language is of Semitic origin; its alphabet consists of twenty-two letters. The number of accents is nearly forty, some of which distinguish the sentences like the punctuation of our language, and others serve to determine the number of syllables, or to mark the tone with which they are to be sung or spoken.

The Hebrew character is of two kinds, the ancient or square, and the modern or rabbinical. In the first of these the Scriptures were originally written. The last is deprived of most of its angles, and is more easy and flowing. The Hebrew words as well as letters are written from right to left in common with, the Semitic tongues generally, and the language is regular, particularly in its conjugations. Indeed, it has but one conjugation, but with seven or eight variations, having the effect of as many different conjugations, and giving great variety of expression. The predominance of these modifications over the noun, the idea of time contained in the roots of almost all its verbs, so expressive and so picturesque, and even the scarcity of its prepositions, adjectives, and adverbs, make this language in its organic structure breathe life, vigor, and emotion. If it lacks the flowery and luxuriant elements of the other oriental idioms, no one of these can be compared with the Hebrew tongue for the richness of its figures and imagery, for its depth, and for its majestic and imposing features.

In the formation, development, and decay of this language, the following periods may be distinguished:—

First. From Abraham to Moses, when the old stock was changed by the infusion of the Egyptian and Arabic. Abraham, residing in Chaldea, spoke the Chaldaic language, then traveling through Egypt, and establishing himself in Canaan or Palestine, his language mingled its elements with the tongues spoken by those nations, and perhaps also with that of the Phoenicians, who early established commercial intercourse with him and his descendants. It is probable that the Hebrew language sprung from the mixture of these elements.

Second. From Moses and the composition of the Pentateuch to Solomon, when it attained its perfection, not without being influenced by the Phoenician. This is the Golden Age of the Hebrew language.

Third. From Solomon to Ezra, when, although increasing in beauty and sweetness, it became less pure by the adoption of foreign ideas and idioms.

Fourth. From Ezra to the end of the reign of the Maccabees, when it was gradually lost in the Aramaean or Chaldaic tongue, and became a dead language.

The Jews of the Middle Ages, incited by the learning of the Arabs in Spain, among whom they received the protection denied them by Christian nations, endeavored to restore their language to something of its original purity, and to render the Biblical Hebrew again a written language; but the Chaldaic idioms had taken too deep root to be eradicated, and besides, the ancient language was found insufficient for the necessities of an advancing civilization. Hence arose a new form of written Hebrew, called rabbinical from its origin and use among the rabbins. It borrowed largely from many contemporary languages, and though it became richer and more regular in its structure, it retained little of the strength and purity of the ancient Hebrew.

3. THE OLD TESTAMENT.—The literary productions of the Hebrews are collected in the sacred books of the Old Testament, in which, according to the celebrated orientalist, Sir William Jones, we can find more eloquence, more historical and moral truth, more poetry,—in a word, more beauties than we could gather from all other books together, of whatever country or language. Aside from its supernatural claims, this book stands alone among the literary monuments of other nations, for the sublimity of its doctrine, as well as for the simplicity of its style.
