51 from the blood of Abel to the blood of Zechariah, who was struck down between altar and sanctuary, is on your heads. Yes, it's on the bill of this generation and this generation will pay.

Matthew Henry's Commentary on Luke 11:51

Commentary on Luke 11:37-54

(Read Luke 11:37-54)

We should all look to our hearts, that they may be cleansed and new-created; and while we attend to the great things of the law and of the gospel, we must not neglect the smallest matter God has appointed. When any wait to catch something out of our mouths, that they may insnare us, O Lord, give us thy prudence and thy patience, and disappoint their evil purposes. Furnish us with such meekness and patience that we may glory in reproaches, for Christ's sake, and that thy Holy Spirit may rest upon us.
