1-е Коринфянам 9:13

minister about holy things--the Jewish priests and Levites. The Greek especially applies to the former, the priests offering sacrifices. partakers with the altar--a part of the victims going to the service of the altar, and the rest being shared by the priests (Lev 7:6; Num 18:6, &c.; Deu 18:1, &c.).

In this chapter the apostle seems to answer some cavils against himself. I. He asserts his apostolical mission and authority, and gives in his success among them as a testimony to it (Co1 9:1, Co1 9:2). II. He claims a right to subsist by his ministry, and defends it by several arguments from natural reason and the Mosaical law, and asserts it also to be a constitution of Christ (Co1 9:3-14). III. He shows that he had willingly waived this privilege and power for their benefit (Co1 9:15-18). IV. He specifies several other things, in which he had denied himself for the sake of other men's spiritual interest and salvation (Co1 9:19-23). And, V. Concludes his argument by showing what animated him to this course, even the prospect of an incorruptible crown (Co1 9:24 to the end.)

9:13 Paul might be referring to Levites and priests at God’s temple in Jerusalem (see Deut 18:1-4; cp. Lev 6:16-17, 26; Num 18:8-32), but the pagan priests in temples around Corinth would have done similarly.
