Translate as Greek, "They all" (namely, who are now with me, Philippians 1:14, Philippians 1:17; Philippians 4:21 : such Demas, then with him, proved to be, Colossians 4:14; compare II Timothy 4:10; Philemon 1:24).
seek their own—opposed to Paul's precept (Philippians 2:4; I Corinthians 10:24, I Corinthians 10:33; I Corinthians 13:5). This is spoken, by comparison with Timothy; for Philippians 1:16-17 implies that some of those with Paul at Rome were genuine Christians, though not so self-sacrificing as Timothy. Few come to the help of the Lord's cause, where ease, fame, and gain have to be sacrificed. Most help only when Christ's gain is compatible with their own (Judges 5:17, Judges 5:23).
