Andrew, Simon Peter's brother. The design of the Evangelist, down to the end of the chapter, is to inform us how gradually the disciples were brought to Christ. Here he relates about Peter, and afterwards he will mention Philip and Nathanael. The circumstance of Andrew immediately bringing his brother expresses the nature of faith, which does not conceal or quench the light, but rather spreads it in every direction. Andrew has scarcely a spark, and yet, by means of it, he enlightens his brother. Woe to our indolence, therefore, if we do not, after having been fully enlightened, endeavor to make others partakers of the same grace. We may observe in Andrew two things which Isaiah requires from the children of God; namely, that each should take his neighbor by the hand, and next, that he should say, Come, let us go up into the mountain of the Lord, and he will teach us, (Isaiah 2:3.) For Andrew stretches out the hand to his brother, but at the same time he has this object in view, that he may become a fellow-disciple with him in the school of Christ. We ought also to observe the purpose of God, which determined that Peter, who was to be far more eminent, was brought to the knowledge of Christ by the agency and ministry of Andrew; that none of us, however excellent, may refuse to be taught by an inferior; for that man will be severely punished for his peevishness, or rather for his pride, who, through his contempt of a man, will not deign to come to Christ.
One of the two which heard John speak,.... The above things, concerning Jesus being the Lamb of God:
and followed him; that is, Jesus, as the Syriac and Arabic versions read; and the Persic version, Christ: and the Ethiopic version, "the Lord Jesus"; for not John, but Jesus they followed:
was Andrew, Simon Peter's brother: see Matthew 4:18 the other, as before observed, might be the writer of this Gospel.
One . . . was Andrew--The other was doubtless our Evangelist himself. His great sensitiveness is touchingly shown in his representation of this first contact with the Lord; the circumstances are present to him in the minutest details; he still remembers the Very hour. But "he reports no particulars of those discourses of the Lord by which he was bound to Him for the whole of His life; he allows everything personal to retire" [OLSHAUSEN].
Peter's brother--and the elder of the two.
One of the two . . . was Andrew. Afterwards an apostle. He has the honor of being one of the first two disciples of Jesus.
Findeth his own brother Simon. Simon Peter. In true missionary spirit Andrew at once and first sought his own brother.
We have found the Messias. The Christ promised by the prophets. Messiah is the Hebrew word meaning the same as Christ.
