Deuteronomy 25:9

他哥哥的妻就要当着长老到那人的跟前，脱了他的鞋，吐唾沫在他脸上，说：『凡不为哥哥建立家室的都要这样待他。』

tā gē ge de qī jiù yào dāng zhe zhǎng lǎo dào nà rén de gēn qián ， tuō le tā de xié ， tǔ tuò mò zài tā liǎn shàng ， shuō ：『 fán bú wèi gē ge jiàn lì jiā shì de dōu yào zhè yàng dài tā 。』

then his brother’s wife shall come to him in the presence of the elders, and loose his sandal from off his foot, and spit in his face. She shall answer and say, “So shall it be done to the man who does not build up his brother’s house.”
