John Wesley on 1 Chronicles 2:55

Scribes - Either civil, who were public notaries, that wrote and signed legal instruments: or ecclesiastical. And these were either Levites, or Simeonites, or rather Kenites, and are here mentioned not as if they were of the tribe of Judah, but because they dwelt among them, and probably were allied to them by marriages, and so in a manner incorporated with them.
