Gevurot 18:24-26 Orthodox Jewish Bible (OJB)
24 Now a certain man, a Yehudi, arrived in Ephesus, Apollos by name, hailing from Alexandria, a lamdan (a Torah scholar with prodigious knowledge), being tief (deep and profound, erudite, keen) in the Kitvei HaKodesh.
25 This one had been taught the Derech Hashem and was on fire in the Ruach Hakodesh and saying shiurim and drashot accurate and true to Rebbe, Melech HaMoshiach. But Rav Apollos was acquainted only with the tevilah of teshuva of Yochanan [see Lk 3:16].
26 And this rabbi began to speak with ometz lev (boldness) in the shul. And having heard him, Priscilla and Aquila took him and more accurately instructed him in the Derech Hashem.
