5:21 {17} I charge [thee] before God, and the Lord Jesus Christ, and the elect angels, that thou observe these things without preferring one before another, doing nothing by partiality.
(17) The fourth rule: let sincerity be used without any prejudice or respect of persons in ecclesiastical proceedings (especially against the elders), because God himself is present there, and the Lord Jesus Christ with a multitude of angels.
5:21 I charge [thee] before God, and the Lord Jesus Christ. The solemnity of this charge shows that Paul had a fear that Timothy's sympathies might lead him aside from a strictly judicial course.
And the elect angels. Why elect we do not certainly know. They may be the good angels as distinct from the bad angels, or those who were chosen to assist in the work of human redemption may be meant. Angels are often mentioned in this connection.
Observe these things. Carry out this discipline
without preferring one before another, doing nothing by partiality. Without respect to persons.
5:21 I charge thee before God - Referring to the last judgment, in which we shall stand before God and Christ, with his elect, that is, holy, angels, who are the witnesses of our conversation. The apostle looks through his own labours, and even through time itself, and seems to stand as one already in eternity. That thou observe these things without prejudging - Passing no sentence till the cause is fully heard. Or partiality - For or against any one.
5:17-25 Care must be taken that ministers are maintained. And those who are laborious in this work are worthy of double honour and esteem. It is their just due, as much as the reward of the labourer. The apostle charges Timothy solemnly to guard against partiality. We have great need to watch at all times, that we do not partake of other men's sins. Keep thyself pure, not only from doing the like thyself, but from countenancing it, or any way helping to it in others. The apostle also charges Timothy to take care of his health. As we are not to make our bodies masters, so neither slaves; but to use them so that they may be most helpful to us in the service of God. There are secret, and there are open sins: some men's sins are open before-hand, and going before unto judgment; some they follow after. God will bring to light the hidden things of darkness, and make known the counsels of all hearts. Looking forward to the judgment-day, let us all attend to our proper offices, whether in higher or lower stations, studying that the name and doctrine of God may never be blasphemed on our account.
