<p>4:1 <i>And as they spoke to the people, t<em>he priests and the captain of the temple guard and the Sadducees</em></i>- The basis of their work was that they were the equivalent of the Levites who kept guard at the gates of the temple, in order to prevent the unclean from entering. They were defining the Jewish Christians and their message of healing as that which was unclean.</p><p><em>Came upon them</em>- This is a common word in Luke-Acts. The Jews had likewise 'come upon' the Lord also in the same temple (Lk. 20:1). Luke is developing his point that the Lord's experiences and sufferings are repeated in those of believers in Him, especially in their work of representing Him in their witness. That principle applies to this day, and is a bridge between Him there so many centuries ago, and us here today.</p>
