{Leap for joy} (skirt(8873)ate). Old verb and in LXX, but only
in Luke in the N.T. (here and  1:41,44 ). It answers to Matthew's
( Mt 5:12 ) "be exceeding glad." {Did} (epoioun). Imperfect
active, the habit of "their fathers" (peculiar to both here).  Mt
5:12  has "persecuted." Thus they will receive a prophet's reward
( Mt 1:41 ).
