Most of us only sing a few of the final stanzas at our seder, but Dayenu actually has 15 stanzas representing the 15 gifts God bestowed. The first five involve freeing the Jews from slavery, the next describe the miracles He did for them, and the last five for the closeness to God He gave them. Each of the stanzas is followed by the word "Dayenu" (it would have been enough) sung repeatedly. The 15 stanzas are as follows:

Five Stanzas of Leaving Slavery

1) If He had brought us out of Egypt.
2) If He had executed justice upon the Egyptians.
3) If He had executed justice upon their gods.
4) If He had slain their first-born.
5) If He had given us their health and wealth.

6) If He had split the sea for us.
7) If He had led us through on dry land.
8) If He had drowned our oppressors.
9) If He had provided for our needs in the wilderness for 40 years.
