“cause the righteous soul to go hungry.” The verb raeb (#07456 רָעֵב) means “to be hungry” in the qal aspect, but this verb is in the hiphil aspect, the causative aspect, and that is important here. There are righteous people who go hungry, but God does not cause it. On a broader note, the Proverb can also be taken to mean that the righteous soul will not be allowed to hunger, but that would be a general statement with plenty of exceptions.
