How was the mitzvah of the willow [performed]? There was a place below Jerusalem called Motza. They descended there, gathered from there large willow branches, and came and stood them up against the sides of the Altar, with their tops drooping over the top of the Altar.  They blew [on a trumpet] a tekiah, a teruah, and a tekiah. Each day they would circle the Altar one time and say, “Please HASHEM bring salvation now, please HASHEM bring success now!” R’ Yehudah says: [They would say,] “ANI VAHO, bring salvation now!” But on that day they circled the Altar seven times.  When they left what did they say? “Beauty is yours, O Altar! Beauty is yours, O Altar!” R’ Eliezer says: [They said,] “To YAH and to you, O Altar! To YAH and to you, O Altar!”

Just as it was performed on the weekdays, so it was performed on the Sabbath, except they gathered them on the eve of the Sabbath and placed them in golden vessels so that they should not wilt.  R’ Yochanan ben Berokah says: They brought date palm branches and beat them on the ground at the sides of the Altar. That day was called the day of the beating of the [date palm] branches.

Immediately the children loosened their lulavim and ate their esrogim.
