Sirach 37:16

16 Let reason go before every enterprise, and counsel before every action.

Sirach 37:16 In-Context

14 For a man's mind is sometime wont to tell him more than seven watchmen, that sit above in an high tower.
15 And above all this pray to the most High, that he will direct thy way in truth.
16 Let reason go before every enterprise, and counsel before every action.
17 The countenance is a sign of changing of the heart.
18 Four manner of things appear: good and evil, life and death: but the tongue ruleth over them continually.
