Marriage
If you fear that you cannot treat orphans fairly, then marry women of your choice, two, three, or four. But if you fear injustice, then marry only one of those already under your care. This will help you avoid wrongdoing.
4:3And if ye fear that ye will not deal fairly by the orphans, marry of the women, who seem good to you, two or three or four; and if ye fear that ye cannot do justice (to so many) then one (only) or (the captives) that your right hands possess. Thus it is more likely that ye will not do injustice.
