From LSJ
οὐχ οὗτός ἐστιν ὁ τοῦ τέκτονος υἱός; οὐχ ἡ μήτηρ αὐτοῦ λέγεται Μαριὰμ καὶ οἱ ἀδελφοὶ αὐτοῦ Ἰάκωβος καὶ Ἰωσὴφ καὶ Σίμων καὶ Ἰούδας; → “Isn't he the carpenter's son? Isn't his mother's name Mary, and aren't his brothers Jacob and Joseph and Shimon and Judah? (Matthew 13:55)
English (LSJ)
οῦ, ὁ,
A first cousin's son, Pherecr.203, Hermipp.86, D.44.26, Is.11.12; also, of second cousins, acc. to Poll.3.28, but this rests on a misinterpretation of D. 45.54.
