Matthew 10:23

But when they persecute you in this city, flee into the next: for verily I say unto you, Ye shall not have gone through the cities of Israel, till the Son of man be come.

Origen in quoting this passage wrote:

Jesus, in teaching his disciples not to be guilty of rashness, gave them (this) precept. He added the example of a consistent life, acting so as not to expose himself to danger, rashly, or unreasonably, or without good grounds.[5]

Likewise, Clement of Alexandria said:

He also who presents himself before the judgment seat becomes guilty of his (own) death. And such is also the case with him who does not avoid persecution, but, out of daring, presents himself for capture.[6]

It is plain that Christ desired that his disciples should avoid bringing against themselves any persecutions due to unwise, rash, or improper conduct; and they were cautioned to avoid animosities by flight whenever possible.

The words "till the Son of man come" do not refer to the final judgment but to the coming of Christ in his kingdom.
