I have come in my Father's name, and you don't receive me. If another comes in his own name, you will receive him.

 The man stands for the people of Israel. The five porches stand for the five books of the law. In the porches the people lay ill. The law could show a man his sin, but could never mend it; the law could uncover a man's weakness, but could never cure it. The law, like the porches, sheltered the sick soul but could never heal it. The thirty-eight years stand for the thirty-eight years in which the Jews wandered in the desert before they entered the promised land; or for the number of the centuries men had been waiting for the Messiah. The stirring of the waters stands for baptism. In point of fact in early Christian art a man is often depicted as rising from the baptismal waters carrying a bed upon his back.
