Gevurot 8:30-32

Orthodox Jewish Bible

³⁰ And having run, Philippos heard him reading Yeshayah HaNavi, and Philippos said, "So do you have binah of what you are reading?"

³¹ And he said, "How then might I be able, unless someone will guide me?" And he invited Philippos to come up and sit with him.

³² Now the keta (section) of the Tanakh which he was reading was this: KASEH LATEVACH YUVAL ("He [Moshiach] was led as a lamb to the slaughter") and as a Seh (Lamb, YESHAYAH 53:7) before the one having sheared it is silent, LO YIFTACH PIV ("He does not open his mouth").
