Charles Ellicott Commentary Proverbs 20

Wine is a mocker, strong drink is raging—that is, producing these effects in those who subject themselves to their power.

The fear of a king is as the roaring of a lion, that is, the dread which he casts upon others when he is becoming angry is a warning of approaching danger.

Sinneth against his own soul— that is, against his own life.

But every fool.— Self-willed person. (Compare to Proverbs 1:22.)

Will be meddling.—Or, rather, showing his teeth: thinking that his own personal dignity is at stake.

Counsel in the heart of man is like deep water. —The wise thoughts of a "man," appropriately so-called , may be hidden deep in his breast, like the waters of a well, but a man of understanding knows how to draw them out as with a windlass and bucket (Exodus 2:16).

Most men will proclaim every one his own goodness.— Will be full of his benevolent intentions, “but a faithful man,” who carries out these promises, “who can find?”
