A.T. Robertson Commentary Luke 6:23

"Rejoice in that day, and leap [for joy]: for behold, your reward is great in heaven; for in the same manner did their fathers unto the prophets." — Luke 6:23 (ASV)

Leap for joy (σκιρτησατε). Old verb and in LXX, but only in Luke in the N.T. (here and 1:41,44). It answers to Matthew's (Matthew 5:12) "be exceeding glad."

Did (εποιουν). 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 1:41).
