🔼The name Sucathites in the Bible
The Sucathites are mentioned only once in the Bible. Apparently they were a family of scribes that lived in Jabez of Judah together with their scribal colleagues the Tirathites and Shimeathites (1 Chronicles 2:55). Collectively these scribal families were known as Kenites and they all seem to have descended from Hammath, the father of the house of Rechab.
🔼Etymology of the name Sucathites
The name Sucathites is obviously an ethnonym, but it's not clear which location this ethnonym points at. It could be a place (or person) named שוכת or שוכה, and the latter form is identical to one of the forms of the name Socoh. And Socoh was a village in the south of Judah, in or near the valley of Elah.
The name Sucathites comes from any of the following verbs:
For a meaning of the name Sucathites, Jones' Dictionary of Old Testament Proper Names reads Dwellers In Booths. Note that when Jeremiah addresses the Rechabites, they tell him that they have always lived in tents, in obedience to the commands of Jonadab, the son of Hammath (Jeremiah 35:10).
BDB Theological Dictionary does not offer an interpretation but lists the Sucathites under the root שוך II (suk II). NOBSE Study Bible Name List doesn't translate our name and declares the Sucathites to be descendants of Caleb, which is incorrect.
