'Passover' in the Bible

And the king commanded all the people, saying, Keep the passover unto the LORD your God, as it is written in the book of this covenant.

Surely there was not holden such a passover from the days of the judges that judged Israel, nor in all the days of the kings of Israel, nor of the kings of Judah;

But in the eighteenth year of king Josiah, wherein this passover was holden to the LORD in Jerusalem.
