Prayer Sandwich Anyone?

Luke 1:9-10 - So it was, that while he was serving as priest before God in the order of his division, 9 according to the custom of the priesthood, his lot fell to burn incense when he went into the temple of the Lord. 10 And the whole multitude of the people was praying outside at the hour of incense. 

Many times Adonai tries to get us to make connections by placing certain things right next to each other.  For example, Luke 1:9-10 has what I call a prayer sandwich!  Notice how the people "praying outside" is sandwiched between to references to "incense".  What do you think this may be teaching us?  Any other Scriptures to support your thoughts?
