Якова 5:9

Grudge not--rather "Murmur not"; "grumble not." The Greek is literally, "groan": a half-suppressed murmur of impatience and harsh judgment, not uttered aloud or freely. Having exhorted them to patience in bearing wrongs from the wicked, he now exhorts them to a forbearing spirit as to the offenses given by brethren. Christians, who bear the former patiently, sometimes are impatient at the latter, though much less grievous. lest . . . condemned--The best manuscript authorities read, "judged." James refers to Mat 7:1, "Judge not lest ye be judged." To "murmur against one another" is virtually to judge, and so to become liable to be judged. judge . . . before the door--referring to Mat 24:33. The Greek is the same in both passages, and so ought to be translated here as there, "doors," plural. The phrase means "near at hand" (Gen 4:7), which in the oldest interpretations [Targums of Jonathan and Jerusalem] is explained, "thy sin is reserved unto the judgment of the world to come." Compare "the everlasting doors" (Psa 24:7, whence He shall come forth). The Lord's coming to destroy Jerusalem is primarily referred to; and ultimately, His coming again visibly to judgment.

In this chapter the apostle denounces the judgments of God upon those rich men who oppress the poor, showing them how great their sin and folly are in the sight of God, and how grievous the punishments would be which should fall upon themselves (Jam 5:1-6). Hereupon, all the faithful are exhorted to patience under their trials and sufferings (Jam 5:7-11). The sin of swearing is cautioned against (Jam 5:12). We are directed how to act, both under affliction and in prosperity (Jam 5:13). Prayer for the sick, and anointing with oil, are prescribed (Jam 5:14, Jam 5:15). Christians are directed to acknowledge their faults one to another, and to pray one for another, and the efficacy of prayer is proved (Jam 5:16-18). And, lastly, it is recommended to us to do what we can for bringing back those that stray from the ways of truth.

5:9 the Judge is standing at the door! The coming of Christ is imminent.
