Proverbs 26:21-23

New Revised Standard Version, Anglicised Catholic Edition

²¹ As charcoal is to hot embers and wood to fire,
    so is a quarrelsome person for kindling strife.
²² The words of a whisperer are like delicious morsels;
    they go down into the inner parts of the body.
²³ Like the glaze^[a] covering an earthen vessel
    are smooth^[b] lips with an evil heart.
