The word(s) "chieftains" appears 12 time(s) in 12 verse(s) in Quran in Muhammad Pickthal translation.

(1) Allah made a covenant of old with the Children of Israel and We raised among them twelve chieftains, and Allah said: Lo! I am with you. If ye establish worship and pay the poor-due, and believe in My messengers and support them, and lend unto Allah a kindly loan, surely I shall remit your sins, and surely I shall bring you into Gardens underneath which rivers flow. Whoso among you disbelieveth after this will go astray from a plain road.

(2) The chieftains of his people said: Lo! we see thee surely in plain error.

(3) The chieftains of his people, who were disbelieving, said: Lo! we surely see thee in foolishness, and lo! we deem thee of the liars.

(4) The chieftains of his people, who were scornful, said unto those whom they despised, unto such of them as believed: Know ye that Salih is one sent from his Lord? They said: Lo! In that wherewith he hath been sent we are believers.

(5) The chieftains of his people, who were scornful, said: Surely we will drive thee out, O Shu'eyb, and those who believe with thee, from our township, unless ye return to our religion. He said: Even though we hate it?

(6) But the chieftains of his people, who were disbelieving, said: If ye follow Shu'eyb, then truly ye shall be the losers.

(7) The chieftains of his folk, who disbelieved, said: We see thee but a mortal like us, and we see not that any follow thee save the most abject among us, without reflection. We behold in you no merit above us - nay, we deem you liars.

(8) And he was building the ship, and every time that chieftains of his people passed him, they made mock of him. He said: Though ye make mock of Us, yet We mock at you even as ye mock;

(9) But the chieftains of his folk, who disbelieved, said: This is only a mortal like you who would make himself superior to you. Had Allah willed, He surely could have sent down angels. We heard not of this in the case of our fathers of old.

(10) And the chieftains of his folk, who disbelieved and denied the meeting of the Hereafter, and whom We had made soft in the life of the world, said: This is only a mortal like you, who eateth of that whereof ye eat and drinketh of that ye drink.
