Kumbukumbu La Torati 25:9

mjane wa nduguye atamwendea mbele ya wazee, atamvua kiatu kimoja na kumtemea mate usoni, na kusema, “Hivi ndivyo ambavyo hufanywa kwa mtu ambaye atakataa kuendeleza jamaa ya ndugu yake.”

Then shall his brother’s wife come unto him in the presence of the elders, and loose his shoe from off his foot, and spit in his face, and shall answer and say, So shall it be done unto that man that will not build up his brother’s house.
