Aside from 1 Cor. 9:13, the Greek adjective “hieron” is limited to Matthew, Mark, Luke, John, and Acts.  This term, which meant “temple” or “sanctuary,” is used several times in each of these books.  This term first occurs in conjunction with Jesus’ temptations in Mt. 4:5.  Acts 2:46 tells us the first Christians used the Jewish temple as a place to assemble.
