In apartheid South Africa 16 December was known as Day of the Vow, as the Voortrekkers in preparation for the battle on 16 December against the Zulus took a Vow before God that they would build a church and that they and their descendants would observe the day as a day of thanksgiving should they be granted victory.
Hiti 16 December vateke xiboho emahlweni ka Xikwembu, xaleswaku loko vo hlula ma Zulus, vata aka kereke, naswona valandzeri vavona vata teka siku leri tani hi siku ro hisela magandzelo.
