And say to Archippus - Archippus is mentioned also in Philemon 1:2. He is not elsewhere referred to in the New Testament, and nothing further is known of him.
Take heed to the ministry ... - The Greek here is, τὴν διακονίαν tēn diakonian - meaning the office of ministering in divine things; but it is not certain precisely what office he held there. It seems probable from the language which the apostle applies to him - “the ministry” - (compare Acts 1:17, Acts 1:25; Acts 6:4; Acts 20:24; Acts 21:19; Rom 11:13; 1 Corinthians 12:5; 2 Corinthians 3:7-9; 2Co 4:1; 2 Corinthians 5:18; 2 Corinthians 6:3; Ephesians 4:12), that he was not a deacon, properly so called, but that he was a preacher of the word. In Philemon 1:2, he is mentioned by Paul as his “fellow-soldier,” and it is evident that the apostle meant to speak of him with honor. There is no evidence, as has been supposed by some, that he intended to imply, by what he said, that he had been remiss in the performance of his duties, but the apostle doubtless meant to encourage him and to excite him to increased ardor and zeal in the work of the Lord; compare the notes at Acts 20:28. It is always proper to caution even the most faithful and self-denying servants of the Lord to “take heed,” or see to it, that they perform their duties with fidelity. The office of the ministry is such, and the temptations to unfaithfulness are so great, that we need constant watchfulness.
That thou fulfil it - That there be nothing wanting, or lacking, in any of the departments of labor which you are called to perform.
