Origen

(tom. xiii. in Joan. c. 5, 6) May not Jacob’s well signify mystically the letter of Scripture; the water of Jesus, that which is above the letter, which all are not allowed to penetrate into? That which is written was dictated by men, whereas the things which the eye hath not seen, nor ear heard, neither have entered into the heart of man, cannot be reduced to writing, but are from the fountain of water, that springeth up unto everlasting life, i. e. the Holy Ghost. These truths are unfolded to such as carrying no longer a human heart within them, are able to say with the Apostle, We have the mind of Christ. (1 Cor. 11:16) Human wisdom indeed discovers truths, which are handed down to posterity; but the teaching of the Spirit is a well of water which springeth up into everlasting life. The woman wished to attain, like the angels, to angelic and super-human truth without the use of Jacob’s water. For the angels have a well of water within them, springing from the Word of God Himself. She says therefore, Sir, give me this water. But it is impossible here to have the water which is given by the Word, without that which is drawn from Jacob’s well; and therefore Jesus seems to tell the woman that He cannot supply her with it from any other source than Jacob’s well; If we are thirsty, we must first drink from Jacob’s well. Jesus saith unto her, Go, call thy husband, and come hither. (Rom. 7:1) According to the Apostle, the Law is the husband of the soul.
