'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 thou shalt protest solemnly unto them, and shalt show them the manner of the king that shall reign over them.

And the king sent and called for Shimei, and said unto him, Did I not adjure thee by Jehovah, and protest unto thee, saying, Know for certain, that on the day thou goest out, and walkest abroad any whither, thou shalt surely die? and thou saidst unto me, The saying that I have heard is good.

I protest by that glorifying in you, brethren, which I have in Christ Jesus our Lord, I die daily.
