Job 38:18

18 Hast thou perceived the breadth of the earth? declare if thou knowest it all.

Job 38:18 In-Context

16 Hast thou entered into the springs of the sea? or hast thou walked in the search of the depth?
17 Have the gates of death been opened unto thee? or hast thou seen the doors of the shadow of death?
18 Hast thou perceived the breadth of the earth? declare if thou knowest it all.
19 Where is the way where light dwelleth? and as for darkness, where is the place thereof,
20 That thou shouldest take it to the bound thereof, and that thou shouldest know the paths to the house thereof?
