Charles Ellicott Commentary Psalms 10:5

"His ways are firm at all times; Thy judgments are far above out of his sight: As for all his adversaries, he puffeth at them." — Psalms 10:5 (ASV)

His ways are always grievous. —Better, his enterprises always succeed. This meaning is obtained from Job 20:21, nothing escaped his covetousness, therefore his prospering shall not last, and from the cognate of the verb “strength.” Perhaps, however, “his ways are always strong” implies only the bold and reckless course with which a tyrant pursues his end. (Compare to Psalm 73:12.)

Thy judgments... —Literally, a height your judgments far above him. (Compare to Psalm 36:6.)

Puffeth — i.e., in scorn. (Compare to Psalm 12:5.) South uses the word in this sense, “It is really to defy heaven to puff at damnation, and bid omnipotence do its work.” It is especially forcible after the description of the haughty attitude of the wicked, with his nose high in the air, snorting out contempt against his foes, disdaining God and man alike.
