This clip explains that we have to express our gratitude and be thankful for everything God did. All the miracles and everything that God did is stated in the song and after each miracle or each thing, God helped us do we say Dayenu. This means that it would've been enough and that we are thankful for this, however, sometimes we say Lo Dayenu which means it is not enough. We say Lo Dayenu for example when, we are free and some people aren't.
