Knowest thou [it], because thou wast then born? or [because] the number of thy days [is] great? International Standard Version
You should know! After all, you had been born back then, so the number of your days is great!

American Standard Version
Doubtless , thou knowest, for thou wast then born, And the number of thy days is great!
