Jether
The name Jether (also given once as Ithra) belongs to five distinct men in the Hebrew Bible. Two of them appear in narrative settings — Gideon's firstborn son in the wars against Midian, and the father of Amasa whose death by Joab's hand becomes one of David's deathbed grievances. The remaining three are recorded only in the Chronicler's genealogies of Judah and Asher.
Gideon's Firstborn at Karkor
The first Jether is the eldest son of Gideon, brought into the closing scene of the Midianite campaign. After Gideon overtakes the kings Zebah and Zalmunna and learns that they had killed his own brothers at Tabor, he turns to his eldest boy and orders the execution himself: "And he said to Jether his firstborn, Rise up, and slay them. But the youth did not draw his sword; for he feared, because he was yet a youth" (Jud 8:20). The captive kings then ask Gideon to do the deed himself, and he does (Jud 8:21). Jether disappears from the narrative at this single moment, remembered as a boy whose nerve failed him on the field where his father's authority would settle the war.
Father of Amasa, the Ishmaelite
The second and most fully attested Jether is the father of Amasa, the captain whom Absalom set over Israel's army during the rebellion against David. The genealogy in Chronicles is direct: "And Abigail bore Amasa; and the father of Amasa was Jether the Ishmaelite" (1 Ch 2:17). The Samuel parallel calls him by the variant "Ithra" and locates him within David's own kinship network: "And Absalom set Amasa over the host instead of Joab. Now Amasa was the son of a man, whose name was Ithra the Israelite, that entered Abigal the daughter of Nahash, sister to Zeruiah, Joab's mother" (2 Sa 17:25). Amasa was therefore Joab's first cousin through their mothers, and that family tie shapes everything that follows.
After the failure of Absalom's revolt, David moves to displace Joab and install Amasa in his place: "And say⁺ to Amasa, Are you not my bone and my flesh? God do so to me, and more also, if you are not captain of the host before me continually in the place of Joab" (2 Sa 19:13). Amasa's first commission under David follows quickly — "Then the king said to Amasa, Call together for me the men of Judah three days, and be present here" (2 Sa 20:4) — but on the road Joab meets him with a feigned greeting and stabs him. The aftermath is sketched with grim economy: "And Amasa lay wallowing in his blood in the midst of the highway. And when the man saw that all the people stood still, he carried Amasa out of the highway into the field, and cast a garment over him, when he saw that everyone who came by him stood still" (2 Sa 20:12).
David carries the killing as an unsettled debt to the end of his life. On his deathbed he names Amasa, and with him his father Jether, in the charge he lays on Solomon: "Moreover you know also what Joab the son of Zeruiah did to me, even what he did to the two captains of the hosts of Israel, to Abner the son of Ner, and to Amasa the son of Jether, whom he slew, and shed the blood of war in peace, and put the blood of war on his belt that was about his loins, and in his sandals that were on his feet" (1 Ki 2:5). The verdict pronounced over Joab when Solomon executes the charge frames the killings as judicial bloodguilt: "And Yahweh will return his blood on his own head, because he fell on two men more righteous and better than he, and slew them with the sword, and my father David didn't know it, [to wit,] Abner the son of Ner, captain of the host of Israel, and Amasa the son of Jether, captain of the host of Judah" (1 Ki 2:32). In both notices Jether's name survives only as the patronymic attached to a slain commander — but it is the patronymic Solomon's sentence pointedly preserves.
The Genealogical Jethers
Three further men named Jether appear only in the Chronicler's lists. The first stands among the descendants of Jerahmeel of Judah: "And the sons of Jada the brother of Shammai: Jether, and Jonathan; and Jether died without sons" (1 Ch 2:32). The note that he died childless is the only thing said of him.
The second is listed among the sons of Ezrah, in the same Judahite block: "And the sons of Ezrah: Jether, and Mered, and Epher, and Jalon; and she became pregnant with Miriam, and Shammai, and Ishbah the father of Eshtemoa" (1 Ch 4:17).
The last appears among the chiefs of the tribe of Asher, recorded with his three sons: "And the sons of Jether: Jephunneh, and Pispa, and Ara" (1 Ch 7:38). Unlike the Jether of 1 Ch 2:32, this one is remembered as the head of a small line that continues in the tribal register.
