Rock-cut tombs in ancient Israel
The use of rock-cut cave tombs in the region of ancient Israel began in the early Canaanite period, from 3100–2900 BCE. The custom lapsed a millennium, however, before re-emerging in the earliest Israelite tombs, dating to the 9th century BCE in Jerusalem. The use of rock-cut tombs reached its peak in the 8th and 7th centuries BCE, before rapidly declining and eventually falling out of use in the 6th century BCE in some regions.
