Sirach 22:25

25 I will not be ashamed to defend a friend; neither will I hide myself from him.

Sirach 22:25 In-Context

23 Be faithful to thy neighbour in his poverty, that thou mayest rejoice in his prosperity: abide stedfast unto him in the time of his trouble, that thou mayest be heir with him in his heritage: for a mean estate is not always to be contemned: nor the rich that is foolish to be had in admiration.
24 As the vapour and smoke of a furnace goeth before the fire; so reviling before blood.
25 I will not be ashamed to defend a friend; neither will I hide myself from him.
26 And if any evil happen unto me by him, every one that heareth it will beware of him.
27 Who shall set a watch before my mouth, and a seal of wisdom upon my lips, that I fall not suddenly by them, and that my tongue destroy me not?
