HOW DO YOU GREET A YORUBA CHIEF?

In Yoruba culture, a chief is greeted thus ‘ëbä’áfín ö’ ~ by expansion (ëbö á fín)
In English, it means, ‘the sacrifice will be accepted’. Possibly because traditional rulers in those days were largely used to offering sacrifices. The trend of fetish practices is gradually being reduced by the day due to technology and the advent of other religions. For example > muslims and christians pray in stead of offering sacrifices. Prayer in yoruba means ‘àdúrà.
I reasoned within me before asking,’since you know that chief no longer take part in sacrificing but praying, I think they should be greeted thus; àdúråágbà o meaning ‘your prayer will be answered?
