Matthew 18:21

Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him?--In the recent dispute, Peter had probably been an object of special envy, and his forwardness in continually answering for all the rest would likely be cast up to him--and if so, probably by Judas--notwithstanding his Masters' commendations. And as such insinuations were perhaps made once and again, he wished to know how often and how long he was to stand it. till seven times?--This being the sacred and complete number, perhaps his meaning was, Is there to be a limit at which the needful forbearance will be full?

The gospels are, in short, a record of what Jesus began both to do and to teach. In the foregoing chapter, we had an account of his doings, in this, of his teachings; probably, not all at the same time, in a continued discourse, but at several times, upon divers occasions, here put together, as near akin. We have here, I. Instructions concerning humility (Mat 18:1-6). II. Concerning offences in general (Mat 18:7), particularly offences given, 1. By us to ourselves (Mat 18:8, Mat 18:9). 2. By us to others, (Mat 18:10-14). 3. By others to us; which are of two sorts, (1.) Scandalous sins, which are to be reproved (Mat 18:15-20). (2.) Personal wrongs, which are to be forgiven (Mat 18:21-35). See how practical Christ's preaching was; he could have revealed mysteries, but he pressed plain duties, especially those that are most displeasing to flesh and blood.

18:21-35 Peter’s suggestion of seven times was generous, so Jesus’ answer was startling. The disciple’s willingness to forgive should be like God’s forgiving grace, limitless and free (see 18:10-14). Those who do not forgive in this way cannot themselves have experienced God’s forgiveness (18:35; see 6:12).
