NUM25 We must forgo our honor in order to make peace between husband and wife. When the Bais Hamikdosh was in existence, a woman who was suspected of infidelity had a means of proving her innocence. She would come to the Bais Hamikdosh where a priest would give her a special drink in which was placed a section of the Torah with God's name. If she was guilty, she would miraculously die from it. If she was free from guilt, she would benefit from the potion and her innocence would be proven beyond any doubt. Although under normal circumstances it is forbidden to erase God's name, it is permissible in order to make peace between a husband and wife. ... Husbands and wives themselves should overlook slights to their honor in order to facilitate having a peaceful atmosphere in their home. (Maaneh Rach, ch. 12). The Pele Yoatz (section chomov) writes that in-laws should be especially careful not to cause strife and disputes. If the parents of a husband or wife see a fault in their son-in-law or daughter-in-law they should not mention it to their child. Relating such derogatory information can cause much suffering.
