This inscription, written in clear Hebrew (read from right to left), can be translated "For the place of trumpeting to . . . ." It was discovered at the southwestern corner of the Temple Mount. Evidently it had been the upper course of the southwestern corner, and from this position a priest would have blown a trumpet to announce the beginning and end of the sabbath and festivals. Indeed, there is an indentation in the stone where the priest probably stood.
It probably fell from its original position at the top of the southwestern corner of the Temple Mount to the street level below at the time when the Romans destroyed Jerusalem in A.D. 70. This stone is actually a reproduction of the original which was found here.
