Here the warning is against greediness. [source][source][source]
""Give! Give!" [1] can be taken as the names-with more pointed wit than as the cries-of these identical twins, who are made of the same stuff as their mother-other people"s blood." [2][source]
Greediness is not just silly ( Proverbs 30:15), it is dangerous ("Sheol" and "fire," Proverbs 30:16) and pathetic (being childless and parched, Proverbs 30:16). Sheol ever yearns to end life, and the barren womb ever yearns to produce it. [3][source]
