Sirach 37:4-14

4 There is a companion, which rejoiceth in the prosperity of a friend, but in the time of trouble will be against him.
5 There is a companion, which helpeth his friend for the belly, and taketh up the buckler against the enemy.
6 Forget not thy friend in thy mind, and be not unmindful of him in thy riches.
7 Every counsellor extolleth counsel; but there is some that counselleth for himself.
8 Beware of a counsellor, and know before what need he hath; for he will counsel for himself; lest he cast the lot upon thee,
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.
