Luke 17:3 - Ellicott's Commentary On The Whole Bible

Take heed to yourselves. — The position of the words is remarkable, and they have nothing corresponding to them in the parallel passage in Matthew 18:21, where see Note. It is as though our Lord saw in the disciples the tendency to sit in judgment on the sins of others, on such sins especially as He had just condemned, and checked it by the words “take heed to yourselves.” They were in danger of faults hardly less fatal to the spiritual life than selfish luxury, and one of those faults was the temper of hard and unforgiving judgment. When they saw a conspicuous instance of worldliness or other evil, they did as we so often do — they condemned, but did not “rebuke.” In practice, as He taught them by example as by precept, open friendly reproof, aiming at restoration, is the truest path to the forgiveness with which, in the careless estimate of most men, it seems to be incompatible.
