From οἶκος house and νέμω to dispense or manage. Hence οἰκονόμος a house-steward. Here the meaning is stewardship - the office of a steward or administrator in God's house. See on 1Co 9:17, and compare Luk 16:2-4; 1Co 4:1; Tit 1:7; 1Pe 4:10. In Eph 3:2, the word is used of the divine arrangement or economy committed to Paul. In Eph 1:10 of the divine government or regulation of the world.
For you (εἰς ὑμᾶς)
Rev., more strictly, to youward. Connect with was given. The stewardship was assigned to me with you as its object. Compare Eph 3:2; Rom 15:16.
To fulfill (πληρῶσαι)
Fully discharge my office, so that the divine intent shall be fully carried out in the preaching of the Gospel to the Gentiles no less than to the Jews. Compare fully preached, Rom 15:19.
