“When you slaughter a thanks offering to the Lord, you shall slaughter it to garner favor for yourselves” (Leviticus 22:29). “When you slaughter a thanks offering to the Lord,” Rabbi Pinḥas, Rabbi Levi, and Rabbi Yoḥanan in the name of Rabbi Menaḥem of Gaul: In the future, all the offerings will be abolished, but the thanks offering will never be abolished. All forms of thanksgiving will be abolished, but thanksgiving through the thanks offering will never be abolished.
That is what is written: “The sound of gladness and the sound of joy, the sound of a groom and the sound of a bride, the sound of those who say: Give thanks to the Lord of hosts, for the Lord is good” (Jeremiah 33:11); these are the forms of thanksgiving. “Bringing thanks offerings to the House of the Lord” (Jeremiah 33:11); this is the thanks offering. Likewise, David said: “I will fulfill the vows I made to You; I will offer thanks offerings [todot] to You” (Psalms 56:13). It does not say toda,21Singular. but rather todot22Plural. – thanksgiving and a thanks offering.
