For the LORD knoweth the way of the righteous: but the way of the ungodly shall perish. The Lord knoweth - יודע yodea approveth the way, "aloweth the way", Coverdale, of the righteous, צדיקים tsaddikim, from צדק tsadak, to give even weight; the men who give to all their due; opposed to רשעים reshaim, Psalms 1:1, they who withhold right from all; see above. Such holy men are under the continual eye of God's providence; he knows the way that they take; approves of their motives, purposes, and works, because they are all wrought through himself. He provides for them in all exigencies, and defends them both in body and soul.
The way of the ungodly shall perish - Their projects, designs and operations, shall perish; God's curse shall be on all that they have, do, and are. And in the day of judgment they shall be condemned to everlasting fire in the perdition of ungodly men. The wicked shall perish at the presence of the Lord. Reader take warning!
