At this point in the Seder, “we give thanks,” offering songs and words of joy at our
liberation. Even as we remember how much work there is to do, we celebrate the
accomplishments of the past year.
פִּ תְחוּ לִי שַׁעֲרֵי צֶדֶק, אָבאֹ בָם
Open for me the gates of righteousness, and I will enter therein.

(Psalms 118:19, included in the traditional Hallel liturgy)
