Mishnayos Sukkah Perek 4 Mishnah 5

How is the mitzva of the willow branch fulfilled? There was a place below Jerusalem, and it was called Motza. They would descend there and gather willow branches [murbiyyot] from there. And they would then come and stand them upright at the sides of the altar, and the tops of the branches would be inclined over the top of the altar. They then sounded a tekia, a simple uninterrupted blast, sounded a terua, a broken sound and/or a series of short staccato blasts, and sounded another tekia. Each day they would circle the altar one time and say: “Lord, please save us. Lord, please grant us success” (Psalms 118:25). Rabbi Yehuda says that they would say: Ani vaho, please save us. And on that day, the seventh day of Sukkot, they would circle the altar seven times. At the time of their departure at the end of the Festival, what would they say? It is beautiful for you, altar; it is beautiful for you, altar. Rabbi Elazar said that they would say: To the Lord and to you, altar; to the Lord and to you, altar.
