Sirach 37:18LXX

16Whose soul is according to thy own soul: and who, when thou shalt stumble in the dark, will be sorry for thee.

17And establish within thyself a heart of good counsel: for there is no other thing of more worth to thee than it.

18The soul of a holy man discovereth sometimes true things, more than seven watchmen that sit in a high piece to watch.

19But above all these things pray to the most High, that he may direct thy way in truth.

20In all thy works let the true word go before thee, and steady counsel before every action.
