Sirach 10:25

25 Unto the servant that is wise shall they that are free do service: and he that hath knowledge will not grudge when he is reformed.

Sirach 10:25 In-Context

23 It is not meet to despise the poor man that hath understanding; neither is it convenient to magnify a sinful man.
24 Great men, and judges, and potentates, shall be honoured; yet is there none of them greater than he that feareth the Lord.
25 Unto the servant that is wise shall they that are free do service: and he that hath knowledge will not grudge when he is reformed.
26 Be not overwise in doing thy business; and boast not thyself in the time of thy distress.
27 Better is he that laboureth, and aboundeth in all things, than he that boasteth himself, and wanteth bread.
