Sirach 51:21

21 My heart was troubled in seeking her: therefore have I gotten a good possession.

Sirach 51:21 In-Context

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.
23 Draw near unto me, ye unlearned, and dwell in the house of learning.
