'Supplication' in the Bible

and the messenger said unto him, 'Fear not, Zacharias, for thy supplication was heard, and thy wife Elisabeth shall bear a son to thee, and thou shalt call his name John,

But watch ye at every season, making supplication, that ye may prevail to escape all these things that shall come to pass, and to stand before the Son of man.

but I made supplication for thee, that thy faith fail not; and do thou, when once thou hast turned again, establish thy brethren.
