וְשַׁחֲט֖וּ הַפָּ֑סַח וְהִתְקַדְּשׁוּ֙ וְהָכִ֣ינוּ לַאֲחֵיכֶ֔ם לַעֲשׂ֥וֹת כִּדְבַר־יְהוָ֖ה בְּיַד־מֹשֶֽׁה׃ (פ)
Und töte das Passahlamm und heilige dich und bereite dich darauf vor, dass deine Brüder nach dem Wort des HERRN durch die Hand Mose tun.'
Rashi
you have no burden on the shoulders This is another argument and the beginning of a statement. He said to them. You have no more toil of carrying a burden on your shoulders, i.e., all the vessels of the House of the Lord. You can no longer say, “Because of the toil of the burdens on our shoulders, we cannot serve the Lord and His people.” Therefore, from now on, serve the Lord your God with song and His people Israel by slaughtering and flaying their Passover sacrifices, as is proven below (verse 6): “And slaughter the Passover sacrifice and prepare yourselves, etc.”
English Explanation of Mishnah Pesachim
The Israelite killed [the lamb]; If an Israelite wishes to slaughter his own pesah he may do so. Most other sacrifices are slaughtered only by priests. However, in Ezra 6:20 and II Chronicles 30:17, 35:6,11, the Levites are those who slaughter the pesah.
