2:20 Forty and six years. It had been forty-six years since Herod the Great began the reconstruction of the temple, and it was not yet entirely completed. When Jesus was on trial before the Sanhedrin, these words were brought up as blasphemy.
2:20 Forty and six years - Just so many years before the time of this conversation, Herod the Great had begun his most magnificent reparation of the temple, (one part after another,) which he continued all his life, and which was now going on, and was continued thirty - six years longer, till within six or seven years of the destruction of the state, city, and temple by the Romans.
2:12-22 The first public work in which we find Christ engaged, was driving from the temple the traders whom the covetous priests and rulers encouraged to make a market-place of its courts. Those now make God's house a house of merchandise, whose minds are filled with cares about worldly business when attending religious exercises, or who perform Divine offices for love of gain. Christ, having thus cleansed the temple, gave a sign to those who demanded it, to prove his authority for so doing. He foretells his death by the Jews' malice, Destroy ye this temple; I will permit you to destroy it. He foretells his resurrection by his own power; In three days I will raise it up. Christ took again his own life. Men mistake by understanding that according to the letter, which the Scripture speaks by way of figure. When Jesus was risen from the dead, his disciples remembered he has said this. It helps much in understanding the Divine word, to observe the fulfilling of the Scriptures.
