If We willed, We might trample it into pieces then you would remain lamenting.
If we will, we can turn it into hay. Then you will lament:
If We will, We would make it broken stubble and you would remain wondering
If We pleased, We would make it chaff, then would you lament
If We willed/wanted We would have made it debris/crumbs , so you continued/remained regretting/wondering
If it is the Creator Who makes the crops to grow, the He may turn them into hay. Then you will cry
If We will We can make it like dry trampled hay, so you would keep crying out
If WE so pleased, WE could reduce it all to withered stubble, then you would keep lamenting
If We so intend, We would crumble it to pieces. Then you would only be struck with awe and shame
If We (so) pleased We could reduce it to chaff (before it is ripe and ready to be harvested). And then you would remain lamenting and talking bitterly
Were it Our Will, We could crumble it to dry pieces, and you would be regretful (or left in wonderment)
