Proverbs 30:6

Add thou not Do not mix with the pure silver of His words the dross of human speculations. "Noli investigare res quæ mentem humanam transcendunt (Proverbs 30:4), ut doctrinam divinitus patefactam inde compleas." Maurer.

Proverbs 30:7. To the profitable reception of this word of God two things are necessary: first there must be "an honest and good heart," and next there must be a lot removed from the dangerous extremes of wealth and poverty. For these two things therefore he prays earnestly.
