Sirach 24:28

28 The first man knew her not perfectly: no more shall the last find her out.

Sirach 24:28 In-Context

26 He maketh the understanding to abound like Euphrates, and as Jordan in the time of the harvest.

27 He maketh the doctrine of knowledge appear as the light, and as Geon in the time of vintage.

28 The first man knew her not perfectly: no more shall the last find her out.

29 For her thoughts are more than the sea, and her counsels profounder than the great deep.

30 I also came out as a brook from a river, and as a conduit into a garden.
