We have before seen that Paul testifies that the sprinklings of the Mosaic system were baptisms. We now have the added voice of the son of Sirach certifying the same thing. By the mouth of two or three witnesses shall every word be established. These witnesses are ignorant or false, or else _baptizo_ does not here mean, to dip, to immerse. Footnote 31: J. W. Etheridge, in “Jerusalem and Tiberias.” P. 105. This conclusion is yet farther confirmed by the light which the above proverb sheds upon a passage in the writings of Paul, which has greatly perplexed expositors. “Else what shall they do which are baptized for the dead, if the dead rise not at all? why are they then baptized for the dead?”—1 Cor. xv, 29. Paul is discussing the doctrine of the resurrection. As elsewhere in the epistle, so here, he assumes his readers to know the law of Moses. (Compare 1 Cor. ix, 8-10; x, 1-10.) To it, he, therefore, appeals.—“You know that there is in the law an ordinance for the ritual restoration of such as, by contact with the dead, have become ritually dead. But what means this rite? If the saints shall not really be raised up, to what intent is this ritual resurrection?” That such was the meaning of Paul, will hardly be questioned by any who consider, (1.) That the law of defilement by the dead, and of purification with the water of separation, was a statute of universal obligation to Israel, at home, and in foreign lands: (2.) That the ordinance and its observance were so familiar that, two hundred years before Christ, it was made the ground of the proverb above cited. As we shall presently see, it is mentioned by Philo and by Josephus as, in their days, universally observed: (3.) That it was known to Paul by the name of baptism: (4.) That it meant the giving of life to the dead: (5.) That, hence, whatever might be Paul’s allusion, it was a fact, throughout the dwellings of Israel, that, whenever death visited a house, it involved the consequent necessity of the baptism of the family and attendants,—a baptism which signified the resurrection of the dead. It is, therefore, beyond question that Paul meant to refer to that Levitical purification. Such were the facts that his readers could not but so understand him. Moreover, his expression here, and that which we have heretofore examined concerning the divers baptisms of the law, mutually illustrate each other and confirm all our conclusions on the subject.
