Charles Ellicott Commentary 1 Chronicles 4:23

"These were the potters, and the inhabitants of Netaim and Gederah: there they dwelt with the king for his work." — 1 Chronicles 4:23 (ASV)

These were the potters. —Namely, the clans enumerated in 1 Chronicles 4:22.

And those that lived among plants and hedges. —Rather, and inhabitants of Netaim and Gederah. Netaim means “plantations” (Isaiah 17:10). Solomon had pleasure-gardens near Bethlehem. See also the notice of Uzziah’s farms and vineyards (2 Chronicles 26:10). Gederah (Joshua 15:36), a town in the Shephelah.

There they lived with the king. —Literally, with the king in his work they lived there. This seems to say that the potteries of Netaim and Gederah were a royal establishment, as those of Sèvres used to be. Perhaps the linen-weaving of Beth-Ashbea (1 Chronicles 4:21) should be included.
