I was stone silent; ¹  I held back the urge to speak. ²  My frustration grew; ³ 

For with great wisdom comes ¹  great frustration; whoever increases his ²  knowledge merely ³  increases his ⁴  heartache.

When the wicked ¹  see this, they will worry; they will grind their teeth in frustration ²  and melt away; the desire of the wicked will perish. ³ 

For all day long ¹  his work produces pain and frustration, ²  and even at night his mind cannot relax! ³  This also is futile!
