In Exodus 12:13-14 we read, The blood shall be a sign for you on the houses where you live; and when I see the blood I will pass over you, and no plague will befall you when I strike the land of Egypt.
13 Ngati yi ta va xikombiso ehenhla ka tindlu leti mi nga eka tona; ndzi ta vona ngati kutani ndzi hundza ehenhla ka n'wina,+ loko ndzi ba tiko ra Egipta a mi nge weriwi hi khombo ri mi lovisa.
