Leviticus 7:13

יקריב קרבנו על זבח [WITH THE CAKES OF LEAVENED BREAD] HE SHALL OFFER HIS OFFERING WITH THE SACRIFICE — The word קרבנו is redundant (it would have sufficed to say על חלת לחם חמץ יקריבנו), it intimates that the bread is not holy as such (קדוש קדושת הגוף), that it should become invalid by being carried forth from the forecourt, or by the touch of טבול יום (see v. 7) and so as to become incapable of going forth from its holy status to that of non-holy (ordinary) food (as is the case with a sacrifice that is קדוש קדושת הגוף), before the sacrifice is slaughtered (Menachot 78b)

עַל־חַלֹּת֙ לֶ֣חֶם חָמֵ֔ץ יַקְרִ֖יב קׇרְבָּנ֑וֹ עַל־זֶ֖בַח תּוֹדַ֥ת שְׁלָמָֽיו׃

Together with loaves of leavened bread shall he make his offering, these to be added to his peace offering of thanksgiving.
