Leviticus 19:17

ולא תשא עליו חטא [THOU SHALT IN ANY WISE REBUKE THY COMPANION] AND NOT BEAR A SIN ON ACCOUNT OF HIM — i. e. though rebuking him thou shalt not expose him to shame (lit., make his face grow pale) in public, in which case you will bear sin on account of him (cf. Sifra, Kedoshim, Chapter 4 8; Arakhin 16b).

לֹֽא־תִשְׂנָ֥א אֶת־אָחִ֖יךָ בִּלְבָבֶ֑ךָ הוֹכֵ֤חַ תּוֹכִ֙יחַ֙ אֶת־עֲמִיתֶ֔ךָ וְלֹא־תִשָּׂ֥א עָלָ֖יו חֵֽטְא׃

Thou shalt not hate thy brother in thy heart: thou shalt certainly rebuke thy neighbour, and not suffer sin on his account.
