Wist ye not...? — This is, as it were, the holy Child’s defence against the implied reproach in. His mother’s question. Had they reflected, there need have been no seeking; they would have known what He was doing and where He was.
About my Father’s business. — Literally, in the things that are My Father’s — i.e., in His work, the vague width of the words covering also, perhaps, the meaning “in My Father’s house,” the rendering adopted in the old Syriac version. The words are the first recorded utterance of the Son of Man, and they are a prophecy of that consciousness of direct Sonship, closer and more ineffable than that of any other of the sons of men, which is afterwards the dominant idea of which His whole life is a manifestation. We find in a Gospel in other respects very unlike St. John’s, the germ of what there comes out so fully in such words as, “My Father worketh hitherto, and I also work” (John 5:17), “I and My Father are One” (John 10:30). The words are obviously emphasised as an answer to Mary’s words, “Thy father.” Subject unto His parents as He had been before and was afterwards, there was a higher Fatherhood for Him than that of any earthly adoption.
