As a man, Jesus had a human life to live, a human experience to undergo. For thirty silent years he was known among men only as a carpenter in Nazareth, and the Scriptures of the Old Testament were his daily companions. When he emerges into public life, we find him thoroughly versed in the Scriptures. Allusions to them are constant, through all his discourses; he continually refers to them as writings that reflect his own image. "Search the Scriptures," he says, "for they are they that testify of me." The Psalms of David were to Jesus all and more than they can be to any other son of man. In certain of them he saw himself and his future life, his trials, conflicts, sufferings, resurrection, and final triumph foreshadowed. He quoted them to confound his enemies. When they sought to puzzle him with perplexing questions he met them with others equally difficult, drawn from the Scriptures. He asks them:-- "What think ye of the Messiah? whose son is he? They say unto him, the Son of David. He saith unto them, How then doth David in spirit call him Lord, saying, The Lord said unto my Lord, Sit thou on my right hand till I make thine enemies thy footstool? If David then call him Lord, how is he his son?" So, when they ask the question, "Which is the greatest commandment of all?" he answers by placing together two passages in the Old Testament, the one commanding supreme love to God and the other impartial love to man's neighbor. The greatest commandment of all nowhere stands in the Old Testament exactly as Jesus quotes it, the first part being found in Deuteronomy vi. 5, and the second in Leviticus xix. 18. This is a specimen of the exhaustive manner in which he studied and used the Scriptures. Our Saviour quotes often also from the prophets. In his first public appearance in his native village he goes into the synagogue and reads from Isaiah. When they question and disbelieve, he answers them by pointed allusions to the stories of Naaman the Syrian and the widow of Sarepta. When the Sadducees raise the question of a future life, he replies by quoting from the Pentateuch that God calls himself the God of Abraham, Isaac, and Jacob, and God is not the God of the dead, but the God of the living, for all are alive to him. He cites the history of Jonah as a symbol of his own death and resurrection; and at the last moment of his trial before the High Priest, when adjured to say whether he be the Christ or not, he replies in words that recall the sublime predictions in the Book of Daniel of the coming of Messiah to judgment. The prophet says:-- "I saw in my vision, and, behold, One like the Son of man came with the clouds of heaven, and came to the Ancient of days; and there was given unto him dominion and glory and a kingdom, that all people and nations and languages should serve him. His dominion is an everlasting dominion, that shall not pass away or be destroyed."
