Enthusiasm
The umbrella collects two narrative instances of zealous, decisive action — Gideon and Jehu — and reads alongside the broader vocabulary of zeal both wise and unwise. In each case the energy is concrete: a trumpet blown, a battle joined, a king cut down, a sanctuary destroyed.
Gideon's Trumpet and Three Hundred
Gideon's commission moves from secrecy to public confrontation. He is found "beating out wheat in the wine press, to hide it from the Midianites" (Jdg 6:11), and his first response to Yahweh's call is hesitation: "Oh, Lord, with what shall I save Israel? Look, my family is the poorest in Manasseh, and I am the least in my father's house" (Jdg 6:15). He asks a sign (Jdg 6:17), builds an altar called Yahweh-shalom (Jdg 6:24), and then acts — by night, "because he feared his father's household and the men of the city, so that he could not do it by day" (Jdg 6:27).
The decisive turn comes when "the Spirit of Yahweh came upon Gideon; and he blew a trumpet; and Abiezer was gathered together after him" (Jdg 6:34). Yahweh then trims the army down — first by the lapping test ("Everyone who laps of the water with his tongue, as a dog laps, him you will set by himself," Jdg 7:5; "By the three hundred men who lapped I will save you⁺," Jdg 7:7) — and Gideon executes the night raid: "So Gideon, and the hundred men who were with him, came to the outermost part of the camp in the beginning of the middle watch... and they blew the trumpets, and broke in pieces the pitchers that were in their hands" (Jdg 7:19). The battle-cry he gives the three hundred is: "For Yahweh and for Gideon" (Jdg 7:18).
The Midianite princes Oreb and Zeeb fall (Jdg 7:25); the angry Ephraimites are placated by Gideon's diplomatic answer ("Isn't the gleaning of the grapes of Ephraim better than the vintage of Abiezer?... God has delivered into your⁺ hand the princes of Midian," Jdg 8:2-3). Israel offers him a dynasty — "Rule over us, both you, and your son, and your son's son also; for you have saved us out of the hand of Midian" — and he refuses: "I will not rule over you⁺, neither will my son rule over you⁺: Yahweh will rule over you⁺" (Jdg 8:22-23).
The same energetic temper, however, runs into a snare. Gideon collects gold earrings from the spoil and "made an ephod of it, and put it in his city, even in Ophrah: and all Israel went whoring after it there; and it became a snare to Gideon, and to his house" (Jdg 8:27). The same verb of decisive action that drove the rescue produces an idol-object under the deliverer's own roof that all Israel "went whoring after." The land has rest forty years (Jdg 8:28), but the household legacy is mixed — seventy sons by many wives, and a Shechemite concubine's son named Abimelech (Jdg 8:30-31).
Jehu's Drive
Jehu's enthusiasm is announced before he embraces it. He is anointed in secret at Ramoth-gilead by a young prophet sent by Elisha: "I have anointed you king over the people of Yahweh, even over Israel. And you will strike the house of Ahab your master, that I may avenge the blood of my slaves the prophets, and the blood of all the slaves of Yahweh, at the hand of Jezebel" (2Ki 9:6-7). His captains improvise a coronation on the stairs, blowing the trumpet: "Jehu is king" (2Ki 9:13).
The temper is recognizable on the road. The Jezreel watchman names him by his manner before recognizing his face: "the driving is like the driving of Jehu the son of Nimshi; for he drives furiously" (2Ki 9:20). His confrontation with Joram is direct — "Is it peace, Jehu? And he answered, What peace, so long as the whoring of your mother Jezebel and her witchcrafts are so many?" — followed by a bowshot through the heart: "And Jehu drew his bow with his full strength, and struck Joram between his arms; and the arrow went out at his heart, and he sunk down in his chariot" (2Ki 9:22-24).
The sustained operation against the house of Ahab and against Baal worship is then framed by Jehu himself in the language of zeal. To Jehonadab the son of Rechab, climbing into his chariot, Jehu says: "Come with me, and see my zeal for Yahweh" (2Ki 10:16). What follows is a calculated trap: a sham assembly summoning all Baal's worshippers — "Ahab served Baal a little; but Jehu will serve him much... I have a great sacrifice [to do] to Baal" (2Ki 10:18-19) — followed by mass execution and the demolition of the Baal temple. "And they broke down the pillar of Baal, and broke down the house of Baal, and made it an outside latrine, to this day. Thus Jehu destroyed Baal out of Israel" (2Ki 10:27-28).
The same intensity has a limit. "Nevertheless from the sins of Jeroboam the son of Nebat, with which he made Israel to sin, Jehu didn't depart from after them, [to wit,] the golden calves that were in Beth-el, and that were in Dan" (2Ki 10:29). Jehu's zeal for Yahweh ends at the calf-cult he inherits. Hosea later announces judgment on the dynasty: "Call his name Jezreel; for yet a little while, and I will avenge the blood of Jezreel on the house of Jehu" (Hos 1:4).
Zeal Without Knowledge
Outside these narrative instances, the rows attach a corrective register to the same temper. Of his Jewish countrymen Paul writes, "I bear them witness that they have a zeal for God, but not according to knowledge" (Rom 10:2) — an enthusiasm misdirected by ignorance. The Maccabean writings hold up zeal for the law as the founding act of the revolt — Mattathias "saw and was zealous, and his reins trembled, and his wrath was kindled... and running on him he slew him on the altar" (1Ma 2:24); his rallying call is "Every one who has zeal for the law, and maintains the covenant, let him follow me" (1Ma 2:27); his deathbed charge is "be⁺ zealous for the law, And give your⁺ souls for the covenant of your⁺ fathers" (1Ma 2:50); his exemplar is "Elijah, while he was full of zeal for the law" (1Ma 2:58). The same writings flag the failure mode: when other commanders, "desiring to do manfully," go out to battle "unadvisedly," they fall (1Ma 5:67). Sirach gives the same caution applied to private life: "Do not be zealous to give your soul to a woman; So that you cause her to walk on your high places" (Sir 9:2).
The Synoptic gospels show enthusiasm overflowing the prohibitions placed on it. The cleansed leper "began to publish it much, and to spread abroad the matter, insomuch that Jesus could no more openly enter into a city" (Mk 1:45); the deaf man's circle, "the more he charged them, so much the more a great deal they published it" (Mk 7:36). And in Gethsemane, the impulsive disciple's sword: "a certain one of those who stood by drew his sword, and struck the slave of the high priest, and took off his ear" (Mk 14:47).
