John Gill Commentary 1 Chronicles 5:16

"And they dwelt in Gilead in Bashan, and in its towns, and in all the suburbs of Sharon, as far as their borders." — 1 Chronicles 5:16 (ASV)

And they dwelt in Gilead
In that part of it which belonged to the tribe of Gad: in Bashan, and in her towns; (See Gill on 1 Chronicles 5:11),

and in all the suburbs of Sharon, upon their borders ;
there were two Sharons, one to the west of the land of Israel near the Mediterranean sea, which is mentioned in (Acts 9:35) as near Lydda and Joppa; and the other to the east or northeast, beyond Jordan, which is here meant.
