Titus 1:6

if anyone is above reproach , the husband of one wife , and his children are believers and not open to the charge of debauchery or insubordination .

An elder must be blameless, faithful to his wife, a man whose children believe and are not open to the charge of being wild and disobedient.

If any be blameless, the husband of one wife, having faithful children not accused of riot or unruly.
