1 Timothy (1 Ti) 3:8-13

Likewise, the shammashim must be of good character, people whose word can be trusted. They must not give themselves to excessive drinking or be greedy for dishonest gain. They must possess the formerly hidden truth of the faith with a clean conscience. And first, let them be tested; then, if they prove themselves blameless, let them be appointed shammashim. Similarly, the wives must be of good character, not gossips, but temperate, faithful in everything. Let the shammashim each be faithful to his wife, managing his children and household well. For those who serve well as shammashim gain good standing for themselves and much boldness in the trust that comes through Yeshua the Messiah.
