Jerusalem dates back to the 8th Century but NOW, archaeologists have found older text, not in Hebrew, from the time of Kings David or Solomon.
Hebrew University archaeologists have found the oldest known alphabetical inscription from Jerusalem, dating back to the period of Kings David or Solomon, 250 years before the previously oldest known written text.The inscription was found near the Temple Mount but is not in Hebrew and was from the pre-Temple period, in the language of one of the peoples who occupied Israel at the time, according to the archaeologists.
Reading from left to right, the text contains a combination of letters approximately 2.5 cm tall, which translate to m, q, p, h, n, (possibly) l, and n. Since this combination of letters has no meaning in known west-Semitic languages, the inscription’s meaning is unknown
