Ammiel
Ammiel is the name borne by four distinct men in the Hebrew Bible: a Danite spy in the wilderness generation, a man of Lo-debar whose son Machir sheltered Saul's surviving heir and later supplied David in flight, the father of Bath-sheba (also called Eliam), and a Levitical gate-keeper among the sons of Obed-edom. The four occurrences sit in three quite different narrative settings — the Mosaic scouting of Canaan, the David court chronicles, and the Chronicler's roster of the doorkeeper courses — and each Ammiel is identified by a different patronymic or family-of-origin, so they are kept as four separate entries.
The Danite Spy
The first Ammiel appears in the roll of the twelve men whom Moses commissions to scout the land. The tribal roster names him as Dan's representative: "Of the tribe of Dan, Ammiel the son of Gemalli" (Num 13:12). The naming-clause sits within the larger sending-scene where the spy-corps is exhibited as the Mosaic-commissioned twelve-tribe scouting party — "These are the names of the men who Moses sent to spy out the land. And Moses called Hoshea the son of Nun Joshua" (Num 13:16). Ammiel of Dan is one of the twelve dispatched scouts; the text gives him no individual report, only his place in the roster.
The Man of Lo-debar, Father of Machir
The second Ammiel is known only as the father of Machir of Lo-debar. He himself never speaks or acts; his name surfaces twice as a patronymic in the David narratives.
The first appearance comes when David asks whether any Saulide remains to whom he can show kindness. Ziba's answer locates the lame Mephibaal in Trans-jordan: "And the king said to him, Where is he? And Ziba said to the king, Look, he is in the house of Machir the son of Ammiel, in Lo-debar" (2Sa 9:4). David then sends and recovers him: "Then King David sent, and fetched him out of the house of Machir the son of Ammiel, from Lo-debar" (2Sa 9:5). Ammiel is the patronymic by which Machir's house is named in the very moment Saul's grandson is conveyed out of its shelter into the king's table-fellowship.
The second appearance is at Mahanaim during Absalom's revolt, when David's trans-Jordan supporters meet him with relief supplies: "And it came to pass, when David came to Mahanaim, that Shobi the son of Nahash of Rabbah of the sons of Ammon, and Machir the son of Ammiel of Lodebar, and Barzillai the Gileadite of Rogelim" (2Sa 17:27). Ammiel is again the patronymic that places Machir, this time alongside Shobi and Barzillai, as one of the trans-Jordan magnates who provision the fleeing king. The two scenes form an inclusio: the house "of Machir the son of Ammiel" first hides a Saulide and later supplies David himself.
The Father of Bath-sheba (Eliam)
The third Ammiel is given by the Chronicler as the father of David's wife Bath-shua, in the Jerusalem birth-list of David's sons: "and these were born to him in Jerusalem: Shimea, and Shobab, and Nathan, and Solomon, four, of Bath-shua the daughter of Ammiel" (1Ch 3:5). The Chronicler's "Ammiel" stands behind the four Jerusalem-born sons including Nathan and Solomon.
The Chronicler's "Ammiel" is identified as the same person also called "Eliam" in the Samuel narrative. In Samuel the patronymic is given at the moment David sends to inquire who the woman on the roof is: "And David sent and inquired after the woman. And one said, Isn't this Bathsheba, the daughter of Eliam, the wife of Uriah the Hittite?" (2Sa 11:3). The same father is therefore named "Eliam" at the start of the Bath-sheba episode in 2 Samuel 11 and "Ammiel" in the Chronicler's later genealogical summary.
The Sixth Son of Obed-edom
The fourth Ammiel appears in the Chronicler's gate-keeper courses as the sixth son of Obed-edom. The roster gives Obed-edom's sons by birth-rank: "And Obed-edom had sons: Shemaiah the firstborn, Jehozabad the second, Joah the third, and Sacar the fourth, and Nethanel the fifth, Ammiel the sixth, Issachar the seventh, Peullethai the eighth; for God blessed him" (1Ch 26:4-5). Ammiel here is not a patronymic but a personal name within the Levitical doorkeeper line, and the closing clause "for God blessed him" attaches the eight-son roster to the long-term fertility of Obed-edom's house in the David-organized service of the house of Yahweh.
The Four in Summary
The four Ammiels are kept separate by patronymic, role, and period: Ammiel son of Gemalli of Dan in the wilderness scouting (Num 13:12); Ammiel of Lo-debar, father of Machir, in the David narratives (2Sa 9:4, 9:5; 17:27); Ammiel father of Bath-shua / Bath-sheba, also called Eliam (1Ch 3:5; 2Sa 11:3); and Ammiel sixth son of Obed-edom in the Levitical doorkeeper roster (1Ch 26:5). The texts never link the four to one another, and they appear in unrelated narrative blocks.
