פּירוש אויף דברים 26:11

ושמחת בכל הטוב AND THOU SHALT REJOICE IN EVERY GOOD THING — From this they (the Rabbis) derived the law that the recital on the occasion of bringing the first fruits is made only during the joyful period of the year — from Pentecost till the Feast of Tabernacles — when a man is gathering in his grain, his fruits, his wine and his oil; but from Tabernacles onwards until Chanucah if he brings these, he does not make the recital (Pesachim 36b).

you, and the Levite, and the alien means that you are obliged to gladden them with the fruit of the earth.

concerning the words “נותן לך ושמת בטנא,” (from verse 2) the vowel kametz under the letter ל of the word לך was justified as it represented the end of the speech. When the word לך has the vowel kametz under the letter ך, this indicates that it belongs to what came before.

אתה והלוי THOU AND THE LEVITE — the Levites are also bound to bring the first fruits to the priest if they planted anything in the fields attached to their cities.
