'Protest' in the Bible

And Judah spake unto him, saying, The man did solemnly protest unto us, saying, Ye shall not see my face, except your brother be with you.

Now therefore hearken unto their voice: howbeit yet protest solemnly unto them, and shew them the manner of the king that shall reign over them.

I protest by your rejoicing which I have in Christ Jesus our Lord, I die daily.
