Sirach 22:24-26

Revised Standard Version

²⁴ The vapor and smoke of the furnace precede the fire;
    so insults precede bloodshed.
²⁵ I will not be ashamed to protect a friend,
    and I will not hide from him;
²⁶ but if some harm should happen to me because of him,
    whoever hears of it will beware of him.
