Dathan
It means “fountain” in Hebrew but also if considered from the foreign root דת (dat), could means “decree” or “well”. It was an Israelite mentioned in the Old Testament as a participant of the Exodus. He was a son of Eliab, the son of Pallu, the son of Reuben. Together with his brother Abiram, the Levite Korah and others, he rebelled against Moses and Aaron. The Book of Numbers relates that “the earth opened her mouth, and swallowed them up, and their houses.” (Book of Numbers 16, 31)
There’s only one Dathan in the Bible. He and his brother Abiram, sons of Eliab of Reuben, and 250 elders of Israel joined Korah the son of Izhar of Levi in a rebellion against Moses and Aaron (Numbers 16, 1). When Moses wanted to talk with them, Korah listened to his explanations but Dathan and Abiram wouldn’t even show up (16, 12). Their fate was dire. The two brothers and their families whom they obviously had contaminated with their insolent ideas, descended live into Sheol along with Korah (16, 27, also see 26, 11). The 250 others were incinerated (16, 35) and their fire pans were hammered into plating for the altar as a continuing reminder to everybody that only the descendants of Aaron could approach the tabernacle and burn incense to YHWH (16, 40). The sin of Dathan and Abiram was obviously so utterly grim that their story was told again in Numbers 26, 9 again in Deuteronomy 11, 6 and once more in Psalm 106, 17.
