An ancient teaching about calling down judgment on others by Weekend Fisher over at Heart, Mind, Soul, and Strength
Sarai said to Abram, "The wrong done me is your fault. I myself put my maid in your bosom; now that she sees she is pregnant, I am lowered in her esteem. The LORD decide between you and me." (Genesis 16:5)
So how did that work out for her, calling down God as judge between herself and her husband? In later years:
And Sarah died ... Abraham came to mourn for Sarah, and to weep for her. (Genesis 23:2)
From this the ancient Israelites derived the teaching:
He who calls down divine judgment on his neighbor is himself punished first. (Talmud, Rosh HaShanah 16b)
