Rashi on Genesis 44:7/רש"י על בראשית מ״ד:ז׳

1חלילה לעבדיך FAR BE IT FROM TIIY SERVANTS — It is a degradation (חולין a profane thing) — this is an expression denoting a shameful act. The Targum חס לעבדיך “a sparing to thy servants!” signifies “May there be a sparing from God upon us that we should not do this thing” The expression חס ושלום occurs often in the Talmud in this sense — Forbearance and peace!
