As to the שְׁפֵלָה, see on Jos 15:33. הַגְּדֵרִי, he who was born in Geder, not Gedera, for which we should expect הַגְּדֵרָתִי (1Ch 12:4), although the situation of Gedera, south-east from Jabne (see on Jos 12:4), appears to suit better than that of גֶּדֶר or גְּדֹור in the hill country of Judah; see Jos 12:13 and Jos 15:58.
