Fausset's Bible Dictionary [1]

("heaps", or else "springs".)  1 Samuel 25:44;  Isaiah 10:30, "daughter of Gallim," i.e. Gallim and her sons, i.e. inhabitants. It is enumerated amidst towns of Benjamin; Laish is one. Possibly "Phalti the son of Laish who was from Gallim" was a native of Laish the town, and this a dependency only. Now the hill Khirbet el Jisr, S. of Gibeah of Saul (Valentiner).

Hastings' Dictionary of the Bible [2]

GALLIM (‘heaps’). A place near Jerusalem (  1 Samuel 25:44 ). It is personified, along with Anathoth and other towns, in   Isaiah 10:30 . It is generally placed to the N. of Jerusalem, but the exact site is unknown.

Morrish Bible Dictionary [3]

Apparently a city of Benjamin, associated with Laish, Aiath, Migron, etc., also in Benjamin. 1 Samuel 25:44;  Isaiah 10:30 .

(Heb. Gallim', גִּלִּים , Heaps, or perhaps Fountains), a place emwhich is twice mentioned in the Bible:

1. As the native place of the man to whom Michal, David's wife, was given "Phalti, the son of Laish, who was from Gallim" ( מִגִּלִּים ,  1 Samuel 25:44; Sept. Ρόμμα ; Josephus Γεθλά , Ant. 6:13, 8); but there is no clew to the situation of the place. In  2 Samuel 3:15-16, where Michal returns to David at Hebron, her husband is represented as following her as far as Bahurim, i.e., on the road between the Mount of Olives and Jericho, (comp.  2 Samuel 16:1). But even this does not necessarily point to the direction of Gals lim, because Phalti may have been at the time with Ishbosheth at Mahanaim, the road from which would naturally lead past Bahurim.

2. The name occurs again in the catalogue of places terrified at the approach of Sennacherib ( Isaiah 10:30; Sept. Γαλλείμ ) "Lift up thy voice, O daughter (i.e., inhabitant) of Gallim! attend, O Laish! poor Anathoth!" The other towns in this passage Aiath, Michmash, Ramah, Gibeah of Saul are all, like Anathoth, in the tribe of Benjamin, a short distance north of Jerusalem. It should not be overlooked that in both these passages the names Laish and Gallim are mentioned in connection. Possibly the Ben-Laish in the former implies that Phalti was a native of Laish, that being dependent on Gallim. Its site was unknown to Eusebius and Jerome (Onomast. s.v. Γαλλεί , Gallim), although from hearsay ( Λἐγεται ) they place a village of a similar name ( Γαλλαϊ v Α ) near Accaron (Ekron). Schwarz (Palest. page 131) reports a Beit-Djallin between Ramleh and Joppa, but by other explorers the name is given as Beit-Dejan. Porter suggests the little village of Himseh as a suitable locality (Handb.For Syria, page 214); but there are no ruins there, as at Khirbet El-Haiyeh (Ruins of the Serpents), on a low tell, a little farther N.E., containing the remains of an ordinary village, with a cistern in the middle (Robinson, Later Researches; page 288).

Among the names of towns added by the Sept. to those of Judah in  Joshua 15:59, Gallim ( Γαλλίμ v.r. Γαλέμ ) occurs between Karem and Thether. In  Isaiah 15:8, the Vulgate has Gallirm for Eglaim, among the towns of Moab.

International Standard Bible Encyclopedia [7]

gal´im ( גּלים , gallı̄m ), "heaps"): Probably two distinct places:

(1) A town mentioned among the 11 additional cities of Judah which are in the Septuagint appended to  Joshua 15:59 , and have altogether disappeared from the Hebrew text. It occurs between Karem ( ‛Ain Kairem ) and Baither ( Bettı̂r ); it is probably the large and flourishing village of Beit Jāla , near Bethlehem.

(2) Gallim is mentioned in  Isaiah 10:30; not far from Laishah and Anathoth and certainly North of Jerusalem. It was the home of Palti the son of Laish ( 1 Samuel 25:44 ), and it is by many authorities identified with the Gilgal on the North border of Judah ( Joshua 15:7 ), the Gelı̄lōth of the parallel passage ( Joshua 18:17 ), and the Beth-gilgal of  Nehemiah 12:29 .
