Sirach 30:20

20 He seeth with his eyes and groaneth, as an eunuch that embraceth a virgin and sigheth.

Sirach 30:20 In-Context

18 Delicates poured upon a mouth shut up are as messes of meat set upon a grave.
19 What good doeth the offering unto an idol? for neither can it eat nor smell: so is he that is persecuted of the Lord.
20 He seeth with his eyes and groaneth, as an eunuch that embraceth a virgin and sigheth.
21 Give not over thy mind to heaviness, and afflict not thyself in thine own counsel.
22 The gladness of the heart is the life of man, and the joyfulness of a man prolongeth his days.
