🔼The name Shepham in the Bible
This town called Shepham may have dropped off the Biblical map, but it appears to have remained until the time of David. One of his officers was Zabdi the Shiphmite (שפמי; 1 Chronicles 27:27), and that ethnonym would describe someone from Shepham (or possibly a descendant of a man called Shapham, but in the paragraph in which this ethnonym appears, all ethnonyms seem to point at places and not patriarchs).
🔼Etymology of the name Shepham
It's not clear how the name Shepham is formed but it probably has to do with either the root שפה (shapa) or שפף (shpp):
For a meaning of the name Shepham, Jones' Dictionary of Old Testament Proper Names reads Bald. BDB Theological Dictionary neither translates this name nor lists it under any particular root. Here at Abarim Publications we surmise that this name is similar to the name Saph and derives from the function of the Gatekeeper. This would be a fitting name for a border town.
