Sirach 7:18

18 Change not a friend for any good by no means; neither a faithful brother for the gold of Ophir.

Sirach 7:18 In-Context

16 Number not thyself among the multitude of sinners, but remember that wrath will not tarry long.
17 Humble thyself greatly: for the vengeance of the ungodly is fire and worms.
18 Change not a friend for any good by no means; neither a faithful brother for the gold of Ophir.
19 Forego not a wise and good woman: for her grace is above gold.
20 Whereas thy servant worketh truly, entreat him not evil. nor the hireling that bestoweth himself wholly for thee.
