To have a share in something together with others, to participate jointly in benefits or duties. In 1 Corinthians 9:13, Paul argues that those serving at the altar 'share in what is offered on the altar'—they partake of the sacrificial meals as part of their priestly service. The word emphasizes joint participation in something divided among multiple parties. Paul uses this Old Testament pattern to justify financial support for Christian ministers: if temple workers share in temple provisions, gospel workers should share in gospel support.
