Among the religious reforms are mentioned the purification of the Temple, which had been closed by Achaz, the irreligious predecessor of Ezechias (II Chronicles 28-29), the resumption and proper celebration of the feast of the Passover which had been neglected (II Chronicles 30), and in general the extirpation of idolatry, and the reorganization of the Hebrew worship (II Kings 18, II Chronicles 31). The title prefixed to the twenty-fifth chapter of Proverbs states that the sayings contained in the following collection (25-29) were copied out by the "men of Ezechias." This would seem to indicate, on the part of the king, some literary interest and activity, and in the Talmudic tradition, these "men of Ezechias" are credited with the composition of several books of the Old Testament. Soon after his accession to the throne Ezechias threw off the yoke of the Assyrians, to whom his father had become a vassal (II Kings 18:). Other notable events of his reign are his sickness and miraculous cure, the embassy of Berodach Baladan, and the invasion of Sennacherib. The story of the sickness of Ezechias is narrated in II Kings 20, and in Isaiah 28.
The king having been stricken with some mortal disease, the prophet Isaiah comes in the name of Yahweh to warn him to put his affairs in order, for he is about to die. But Ezechias prays to the Lord, Who sends the prophet back to announce to him that he will recover, and that fifteen years are to be added to his life. As a sign of the fulfillment of this promise, Isaiah causes the shadow to recede a distance of ten lines on the sundial.
However, when in addition to this, the Assyrian demanded the surrender of Jerusalem with a view to carrying its inhabitants into exile, the courage of Ezechias was revived, and he prepared himself for a vigorous resistance. Haughty demands of surrender were repulsed, and the king taking counsel with the prophet Isaiah turned in supplication to Yahweh; he received the assurance that the enemy would soon abandon the siege without doing any harm to the city. This prophecy was shortly verified when after the angel of the Lord slew in the night 185,000 of the besieging forces, the remainder fled with Sennacherib, and returned to Assyria. Echezias survived this deliverance only a few years, and he was buried with great pomp in the tomb of the sons of David (II Kings 20:21; II Chronicles 32:33).

In addition, the site itself of the tunnel and the Kidron valley are fundamental for the faithful of both messianic religions – Christianity and Judaism. This talweg and this topographic confluence are simultaneously a line of contact and a line of symbolic confrontation. The original site of the city, it is at the same time the connecting point between the Mount of Olives (the place where the messiah will come in the Jewish religion, adopted by the gospel stories to be the place of Jesus’ arrest) and the Temple Mount (site of the apocalyptic Last Judgment narrative).
