A high look - The evidence of pride, self-conceit, and vanity. A proud heart, from which the high look, etc., come.
And the ploughing - נר ner, lucerna, the lamp, the prosperity and posterity of the wicked; is sin - it is evil in the seed, and evil in the root evil in the branch, and evil in the fruit. They are full of sin themselves, and what they do is sinful.
The plowing - The Hebrew word, with a change in its vowel points, may signify either:
(1) the “fallow field,” the “tillage” of Proverbs 13:23, or
(2) the lamp.
According to: (1) the verse would mean, “The outward signs of pride, the proud heart, the broad lands of the wicked, all are evil.” (2) however, belongs, as it were, to the language of the time and of the book Proverbs 13:9; Proverbs 24:20. The “lamp of the wicked” is their outwardly bright prosperity.
