John 7:14

Now about the midst of the feast Jesus went up into the temple, and taught.

Now about the midst of the feast, [ eedee (G2235) de (G1161) tees (G3588) heortees (G1859) mesousees (G3322)] - rather, 'Now when it was already the midst of the feast.' It might be the 4th or 5th of the eight days during which it lasted.

Jesus went up into the temple, and taught, [ edidasken (G1321)]. The imperfect tense used implies continued, and therefore formal teaching, as distinguished from mere casual sayings. In fact, this appears to have been the first time that He taught thus openly in Jerusalem. He had kept back until the feast was half through, to let the stir about Him subside; and entering the city unexpectedly, He had begun His "teaching" at the temple, and created a certain awe, before the wrath of the rulers had time to break in upon it.
