Robertson's Word Pictures (NT)
For he taught (edidasken gar). Imperfect tense, and the reason given for secrecy. He was renewing again definitely the prediction of his death in Jerusalem some six months ahead as he had done before (Mark 8:31; Matthew 16:21; Luke 9:22). Now as then Jesus foretells his resurrection "after three days" ("the third day," Matthew 17:23).
