Together with these Greek Scriptures of the Old Testament, there have been transmitted to us several other Jewish documents of the same period, written in the same Hellenistic Greek. They are invaluable for the light which they shed upon the history, customs, and modes of thought and language of the Jews of that time; although the attempt of the church of Rome, to exalt some of them to an equal authority with the Scriptures, has tended to fix a stigma on them, as known to us under the name of Apocrypha. Incautious recourse to the rules and definitions of classic Greek is liable to deceive and mislead us in the critical study of the New Testament. But conclusions intelligently deduced from the language of the Septuagint and of the other Jewish writers of that age, are to be respected as of the highest authority on all questions of the New Testament language. On the subject of our present investigation, these authorities shed a flood of light. In them, we first find the verb, _baptizo_, used to designate rites of religious purifying. Once in the Septuagint, and twice in the Apocrypha, it is applied to Hebrew rites of this nature. That the use of the word to designate religious observances is peculiar to the Hellenistic, as contradistinguished from classic Greek, is indisputable; and it is worthy of consideration, how it came to be selected from the Greek vocabulary for this purpose. The Hebrews of Egypt, in their exile from the land of their fathers, had not abandoned but rather augmented their zeal for the institutions of Moses. A circumstance in their own history, which at first might have seemed to threaten a dissolution of the ties that bound them to the temple at Jerusalem, operated in fact to renovate and strengthen them. This was, the erection by some of their number, of a temple at Onias in Egypt, in imitation of that at Jerusalem. Here, the Levitical rites were punctually observed under priests of the Aaronic line and Levites of the sacred tribe. For this they claimed warrant from the prophecy of Isaiah, xix, 19.—“In that day, shall there be an altar to the Lord in the midst of the land of Egypt.” The adherents of this movement do not seem to have been numerous, and its effect was rather to increase the devotion of the people to the temple at Jerusalem, and the ordinances there maintained. Among them, was developed the same disposition which was prevalent in Judea to give undue importance to multiplied rites of purifying; and hence an increased and constant necessity of finding, in the Greek language which they were now adopting, some word suitable to designate these rites. In that language was the verb, _bapto_, meaning (1) to dip; (2) to wet by dipping; (3) to wet, irrespective of the manner; (4) to dye by dipping, and thence, to dye, without respect to mode—even by sprinkling. But, as we have seen, the rites in question were not dippings, nor were they dyeings, and the word was never used by the Jews to designate them.
