David therefore departed thence, and escaped to the cave Adullam: and when his brethren and all his father's house heard it, they went down thither to him.

David therefore went from thence and fled to the cave of Odollam. And when his brethren, and all his father's house had heard of it, they went down to him thither;

And David goeth thence, and is escaped unto the cave of Adullam, and his brethren hear, and all the house of his father, and go down unto him thither;

So David went away from there and took cover in a strong place at Adullam; and his brothers and all his father's people, hearing of it, went down to him there.

Then David went away from there, and he fled to the cave of Adullam. And when his brothers and all of his father's house had heard of it, they descended to him there.

To the cave Adullam - Or rather "of Adullam." Adullam was the name of a town of Judah in the "Shephelah," not far from Bethlehem, and below it. Innumerable caverns, one nearly 100 feet long, are excavated in the soft limestone hills in the neighborhood of Beit-Jibrin. (The cave is placed by Ganneau and Conder on the hill (500 feet high) over 'Aid el Ma or Miyeh.) David's brethren and kinsmen joined him partly from sympathy with him, and partly because their own lives were in jeopardy front Saul's furious enmity.

The cave Adullam - This was in the tribe of Judah, and, according to Eusebius and Jerome, ten miles eastward of what they call Eleutheropolis.

David therefore departed thence, and escaped to the cave (a) Adullam: and when his brethren and all his father's house heard [it], they went down thither to him.
(a) Which was in the tribe of Judah, near Bethlehem.

David therefore departed from thence,.... From Gath, being driven by Achish from his court, and let go by his servants, and glad he was of the deliverance:
and escaped to the cave Adullam; which was no doubt near to a city of the same name in the tribe of Judah, of which See Gill on Joshua 15:35; this being a strong place, and in his own tribe, he might hope to be in greater safety; here he penned his hundred forty second psalm, see Psalm 142:1,
and when his brethren and all his father's house heard it; that he was come thither:
they went down thither to him; to visit and comfort him, counsel and assist him all they could; and chiefly to secure themselves from the rage and malice of Saul, who they might fear would fall upon them, and avenge himself on them for David's sake.

See what weak instruments God sometimes uses, to bring about his own purposes. The Son of David is ready to receive distressed souls, who will be commanded by him. He receives all who come unto Him, however vile and miserable; he changes them into a holy people, and employs them in his service: those who would reign with him must be contented first to suffer with and for him. Observe with what tender concern David provided for his aged parents. The first thing he does is to find them a quiet habitation, whatever became of himself. Let children learn to honour their parents, in every thing consulting their ease and satisfaction. Though highly preferred, and much employed, let them not forget their aged parents. The steps of a good man are ordered by the Lord. And the Lord will preserve his people for their appointed work, however they may be hated and exposed.

DAVID'S KINDRED AND OTHERS RESORT TO HIM AT ADULLAM. (1-Samuel 22:1-8)
David . . . escaped to the cave Adullam--supposed to be that now called Deir-Dubban, a number of pits or underground vaults, some nearly square, and all about fifteen or twenty feet deep, with perpendicular sides, in the soft limestone or chalky rocks. They are on the borders of the Philistine plain at the base of the Judea mountains, six miles southwest from Beth-lehem, and well adapted for concealing a number of refugees.
his brethren and all his father's house . . . went down--to escape the effects of Saul's rage, which seems to have extended to all David's family. From Beth-lehem to Deir-Dubban it is, indeed, a descent all the way.

Having been driven away by Achish, the Philistian king at Gath, David took refuge in the cave Adullam, where his family joined him. The cave Adullam is not to be sought for in the neighbourhood of Bethlehem, as some have inferred from 2-Samuel 23:13-14, but near the town Adullam, which is classed in Joshua 15:35 among the towns in the lowlands of Judah, and at the foot of the mountains; though it has not yet been traced with any certainty, as the caves of Deir Dubban, of which Van de Velde speaks, are not the only large caves on the western slope of the mountains of Judah. When his brethren and his father's house, i.e., the rest of his family, heard of his being there, they came down to him, evidently because they no longer felt themselves safe in Bethlehem from Saul's revenge. The cave Adullam cannot have been more than three hours from Bethlehem, as Socoh and Jarmuth, which were near to Adullam, were only three hours and a half from Jerusalem (see at Joshua 12:15).
