5 But would you know the place also? Again He says in Canticles, I went down into the garden of nuts; for it was a garden where He was crucified. For though it has now been most highly adorned with royal gifts, yet formerly it was a garden, and the signs and the remnants of this remain. A garden enclosed, a fountain sealed, by the Jews who said, We remember that that deceiver said while He was yet alive, After three days, I will rise: command, therefore, that the sepulchre be made sure; and further on, So they went, and made the sepulchre sure, sealing the stone with the guard. And aiming well at these, one says, and in rest You shall judge them. But who is the fountain that is sealed, or who is interpreted as being a well-spring of living water? It is the Saviour Himself, concerning whom it is written, For with You is the fountain of life.
