[It comes down sweet - but] were it Our will, We could make it burningly salty and bitter: why, then, do you not give thanks [unto Us]?

Were it Our Will, We could make it salt (and unpalatable): then why do ye not give thanks?

If We willed We verily could make it bitter. Why then, give ye not thanks?

If We pleased, We could make it saltish; why give you not thanks?

If We willed, We could make it bitter, so why are you not grateful?
