That finding bolsters the credibility of Old Testament verses that credit the tunnel's construction to King Hezekiah, who ruled in the area from 727 B.C. to 698 B.C.
Some scholars had accepted the biblical account, whereas others had argued that inscriptions at the Siloam Tunnel's outlet indicated an excavation date between 200 B.C. and 100 B.C.
