Fausset's Bible Dictionary [1]

 Joshua 18:17. One of the southern bounds of Benjamin, "over against the going up (ascent) of Adummim." Gilgal occupied the same position "before the going up of Adummim" ( Joshua 15:7) on the northern boundary of Judah, which is the southern bound of Benjamin; therefore Grove would substitute "Gilgal" for "Geliloth." Its derivation is Gaalal "to roll"; like the Scotch "links," meaning both the windings of the stream (Geliloth is near the Jordan) and the coasts; whereas Ciccar is the circle of vegetation or dwellings round the bends of the water.

Conder connects Geliloth with the "tells" or mounds of Palestine, which he thinks to be the accumulated refuse of sun-dried bricks, which served as a platform on which others were baked, as at the present day in India and Egypt. They are found in the Jordan valley, and in the plain of Esdraelon. They always occur near water, and in alluvial clay plains, as in the clay lands between Succoth and Zarthan, where Solomon east his temple brasswork.

Hastings' Dictionary of the Bible [2]

GELILOTH (‘stone circles,’   Joshua 18:17 ). Identical with the Gilgal of   Joshua 15:7 , and possibly with the Bath-gilgal of   Nehemiah 12:29 . It was a place on the border of Benjamin and Judah near the Ascent of Adummim. This last was probably in the neighbourhood of Tal‘ at ed-dum , a hill near the so-called ‘Inn of the Good Samaritan’ on the carriage road to Jericho. The word gelîlôth occurs also in the Heb. in   Joshua 13:2;   Joshua 22:10-11 and   Joel 3:4 , and is tr. [Note: translate or translation.] in AV [Note: Authorized Version.] either ‘borders’ or ‘coasts,’ RV [Note: Revised Version.] ‘regions.’

Morrish Bible Dictionary [3]

A place on the border line between Benjamin and Judah.  Joshua 18:17 . In  Joshua 15:7 the same is apparently called GILGAL.

International Standard Bible Encyclopedia [6]

gē̇ - lı̄´loth ( גּלילות , gelı̄lōth ): This word is used for "districts" or "circuits" perhaps indicating the different parts subject to the several lords of the Philistines (  Joshua 13:2 , the King James Version "borders," the Revised Version (British and American) "regions"); for the quarter of the Jordan valley where the eastern tribes built the altar of Ed ( Joshua 22:10 f; the King James Version "border of," the Revised Version (British and American) "region about," Jordan); and apparently, for the whole of Philistia (  Joel 3:4 , the King James Version "coasts of Palestine," the Revised Version (British and American) "regions of Philistia"). But in  Joshua 18:17 , it is clearly used as a place-name. Geliloth lay on the boundary between Judah and Benjamin which passed En-shemesh (probably ‛Ain el - Ḥōd , about 2 miles East of Jerusalem), "and went out to Geliloth, which is over against the ascent of Adummim." From this point it "went down" toward the plain. The place cannot therefore be identified with Gilgal in the Jordan valley. Some point on the road leading from Jericho to Tal‛at ed - Dumm , about 6 miles from Jerusalem, was probably intended, but no identification is possible.

Cyclopedia of Biblical, Theological and Ecclesiastical Literature [7]

(Heb. Geliloth', גְּלַי 7 לוֹת , Circuits [see below]; Sept. Γαλιλώθ ,Vulg. Tumuli), the name of a place on the boundary of Judah and Benjamin, between En-Shemesh and the ascent to Adummim ( Joshua 18:17); apparently another form of the GILGAL (See Gilgal) (q.v.) of the parallel passage ( Joshua 15:7).

The same word is distinctively used (see Stanley, Sinai and Pal. Append. § 23) five times in the original: twice with reference to the provinces of the Philistine heptarchy ("borders of the Philistines,"  Joshua 13:2; "coasts of Palestine," Joel 3 [4]:4); twice to the Circle (See Ciccar) of the Jordan ("borders,"  Joshua 22:10-11); and once (in the sing.) to the District sloping easterly towards the Dead Sea (" country,"  Ezekiel 47:8). Its derivation (from גָּלִל , to Roll) connects it with that of Galilee (q.v.), with which the versions sometimes confound it. (See Topographical Terms).
