<p>1:21 <i>And the people were waiting for Zechariah, and they were wondering at his delay in the temple</i>- As noted on :18, the delay was long because he had apparently argued back with the Angel in denial that his prayers of his youth really could be answered now. It took half an hour to burn the incense (Rev. 8:1-3); the long delay means that he may have argued back with the Angel for at least another half an hour.</p>
