“Do not exchange a friend for money.
Do not exchange a real brother for the gold of Ophir.
Do not dismiss a wise wife.
Do not dismiss a good wife.
Her charm is worth more than gold.”
Continuing with these sayings of Sirach, you should not exchange a friend for money. Neither should you get rid of your brother for the special gold from Ophir, the great gold mining place. You should not dismiss a wise, good, or charming wife because she is worth more than gold. This seems to indicate it might be all right to get rid of an unwise or bad wife.
