Leap for joy (skirthsate). Old verb and in LXX, but only in Luke in the N.T. (here and Matthew 1:41Matthew 1:44 ). It answers to Matthew's ( Matthew 5:12 ) "be exceeding glad." Did (epoioun). Imperfect active, the habit of "their fathers" (peculiar to both here). Matthew 5:12 has "persecuted." Thus they will receive a prophet's reward ( Matthew 10:41 ).
