Barkay initially dated the inscriptions to the late-7th/early-6th centuries BCE, but later revised this date downward to the early 6th century on paleographic grounds (the forms of the delicately incised paleo-Hebrew lettering) and on the evidence of the pottery found in the immediate vicinity. This dating was subsequently questioned by Johannes Renz and Wolfgang Rollig, who argued that the script was in too poor a condition to be dated with certainty and that a 3rd/2nd century BCE provenance could not be excluded, especially as the repository, which had been used as a kind of "rubbish bin" for the burial chamber over many centuries, also contained material from the fourth century BCE.
