'Twenty seventh' in the Bible

And Zimri went in and made an attack on him and put him to death, in the twenty-seventh year that Asa was king of Judah, and made himself king in his place.

In the twenty-seventh year of Asa, king of Judah, Zimri was king for seven days in Tirzah. Now the people were attacking Gibbethon in the land of the Philistines.
