Proverbs 30:9ESV·traditional attribution

be full . . . deny--that is, puffed up by the pride of prosperity. take the name . . . vain--This is not (Hebrew) the form (compare Exo 20:7), but "take" rather denotes laying violent hold on any thing; that is, lest I assail God's name or attributes, as justice, mercy, &c., which the poor are tempted to do.
