As I was doing research for a Bible study, I came across some articles and commentaries about the hallel.  It was a collection of songs that Jews would sing during their festivals and holidays.  These songs have been sung by the Jewish people year after year for thousands of years.  They were written to commemorate stories of Israel’s past that she wasn’t to forget.  They were written to praise God for His work during those stories.  They were written to unite the people who sing them.  Those songs, they would say, are “ours.”
