The word Passover is mentioned in 71 verses in the Bible…
This is the first of 10 references in the Book of Numbers.
It is interesting the provision about the 2nd Passover in verses 9-12 and the provision for the stranger in the land in verse 14. Note that there is only one ordinance for all though.
