Sirach 27:21-23

New Revised Standard Version, Anglicised

²¹ For a wound may be bandaged,
    and there is reconciliation after abuse,
    but whoever has betrayed secrets is without hope.

²² Whoever winks the eye plots mischief,
    and those who know him will keep their distance.
²³ In your presence his mouth is all sweetness,
    and he admires your words;
but later he will twist his speech
    and with your own words he will trip you up.
