Pseudo-Clementine Literature.: Chapter XIII

Chapter XIII.—Clement Instructed by Barnabas.

While I spake these words, and others to the same effect, there arose a great excitement among the crowd; and some as pitying Barnabas, sympathized with me; but others, being senseless, terribly gnashed their teeth against me.  But, as the evening had already come, I took Barnabas by the hand, and by force conducted him, against his will, to my lodging, and constrained him to remain there, lest some one might lay hands on him.  And having spent several days, and instructed me briefly in the true doctrine, as well as he could in a few days, he said that he should hasten into Judæa for the observance of the festival, and also because he wished for the future to consort with those of his own nation.
