Better, faithful is the saying. A favorite phrase in these Epistles. oP. See 1Ti 3:1; 1Ti 4:9; 2Ti 2:11; Tit 3:8.
Worthy of all acceptation (πάσης ἀποδοχῆς ἄξιος)
The phrase only here and 1Ti 4:9. Ἁποδοχή Pasto olxx. Comp. Act 2:41, ἀποδεξάμενοι τὸν λόγον received his word. Πάσης all or every describes the reception of which the saying is worthy as complete and excluding all doubt.
Came into the world (ἦλθεν εἰς τὸν κόσμον)
The phrase is unique in the Pastorals, and does not appear in Paul. It is Johannine. See Joh 1:9; Joh 3:19; Joh 11:27; Joh 12:46.
To save sinners (ἁναρτωλοὺς σῶσαι)
The thought is Pauline, but not the phrase. See Luk 9:56; Luk 19:10.
Chief (πρῶτος)
Or foremost. Comp. 1Co 15:9, and Eph 3:8. This expression is an advance on those.
