Sirach 51:20

20 I directed my soul unto her, and I found her in pureness: I have had my heart joined with her from the beginning, therefore shall I not be forsaken.

Sirach 51:20 In-Context

18 For I purposed to do after her, and earnestly I followed that which is good; so shall I not be confounded.
19 My soul hath wrestled with her, and in my doings I was exact: I stretched forth my hands to the heaven above, and bewailed my ignorances of her.
20 I directed my soul unto her, and I found her in pureness: I have had my heart joined with her from the beginning, therefore shall I not be forsaken.
21 My heart was troubled in seeking her: therefore have I gotten a good possession.
22 The Lord hath given me a tongue for my reward, and I will praise him therewith.
