'Announce' in the Bible

So also the Lord has ordained to those that announce the glad tidings to live of the glad tidings.

For if I announce the glad tidings, I have nothing to boast of; for a necessity is laid upon me; for it is woe to me if I should not announce the glad tidings.

For as often as ye shall eat this bread, and drink the cup, ye announce the death of the Lord, until he come.
