Sirach 38:13

13 There is a time when in their hands there is good success.

Sirach 38:13 In-Context

11 Give a sweet savour, and a memorial of fine flour; and make a fat offering, as not being.
12 Then give place to the physician, for the Lord hath created him: let him not go from thee, for thou hast need of him.
13 There is a time when in their hands there is good success.
14 For they shall also pray unto the Lord, that he would prosper that, which they give for ease and remedy to prolong life.
15 He that sinneth before his Maker, let him fall into the hand of the physician.
