Sirach 37:9-19

9 And say unto thee, Thy way is good: and afterward he stand on the other side, to see what shall befall thee.
10 Consult not with one that suspecteth thee: and hide thy counsel from such as envy thee.
11 Neither consult with a woman touching her of whom she is jealous; neither with a coward in matters of war; nor with a merchant concerning exchange; nor with a buyer of selling; nor with an envious man of thankfulness; nor with an unmerciful man touching kindness; nor with the slothful for any work; nor with an hireling for a year of finishing work; nor with an idle servant of much business: hearken not unto these in any matter of counsel.
12 But be continually with a godly man, whom thou knowest to keep the commandments of the Lord, whose, mind is according to thy mind, and will sorrow with thee, if thou shalt miscarry.
13 And let the counsel of thine own heart stand: for there is no man more faithful unto thee than it.
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.
19 There is one that is wise and teacheth many, and yet is unprofitable to himself.
