Mishnah Sukkah 3:9משנה סוכה ג׳:ט׳
And where in the recitation of hallel would they wave the lulav? They would do so at the verse: “Thank the Lord, for He is good” (Psalms 118:1, 29) that appears at both the beginning and the end of the psalm, and at the verse: “Lord, please save us” (Psalms 118:25); this is the statement of Beit Hillel. And Beit Shammai say: They would wave the lulav even at the verse: “Lord, please grant us success” (Psalms 118:25). Rabbi Akiva said: I was observing Rabban Gamliel and Rabbi Yehoshua and saw that all the people were waving their lulavim, and the two of them waved their lulav only at: “Lord, please save us,” indicating that this is the halakha. With regard to one who was coming along the way and did not have a lulav in his hand to take and fulfill the mitzva while traveling, when he enters his house to eat,he should take the lulav at his table. He interrupts his meal to fulfill the mitzva of lulav. If he did not take the lulav in the morning, he should take it in the afternoon, as the entire day is suited for fulfilling the mitzva of lulav.
