They glide by ¹  like reed ²  boats, like an eagle that swoops ³  down on its prey. ⁴ 

You remove all the wicked of the earth like slag. ¹  Therefore I love your rules. ² 

I will attack you; ¹  I will purify your metal with flux. ²  I will remove all your slag. ³ 

It shatters in pieces like a clay jar, so shattered to bits that none of it can be salvaged. ¹  Among its fragments one cannot find a shard large enough ²  to scoop a hot coal from a fire ³  or to skim off water from a cistern.” ⁴
