Search the Scriptures; the words may be read either imperatively (as our translation readeth them) or indicatively, You do search the Scriptures; that is, of the Old Testament, for the books of the New Testament were not at that time written; but as they had the books of the Old Testament, so they made use of them: Moses was read in the synagogues every sabbath day; and they (the Pharisees especially) were very well versed both in the law and the prophets. For in them ye think ye have eternal life; they did agree that the way of salvation and everlasting life was revealed unto them in the Holy Scriptures; nay, they did judge, that eternal life was to be obtained by their observation of the law. They are they which testify of me: they (saith our Saviour) are my principal testimony; he doth not only say, they testify, but they are they which testify. No writings but those testify of me; I principally appeal to them to give you an account of me.
