Matthew Poole and continuators on Psalms 1:6

6 For the LORD knoweth the way of the righteous: but the way of the ungodly shall perish .

He now gives a reason of this great difference between the righteous and the ungodly, expressed in the foregoing verses.

Either 1. properly and speculatively he searcheth and knoweth all their hearts and ways, or actions; and therefore will Preserve, prosper, and bless them; which may be gathered out of the following and opposite clause of this verse, and out of v. 1, 2. Or 2. practically and affectionately▪ as words of knowledg in Scripture do very frequently imply affection, as Exod. 1. 8. Psal. 31. 7. & 101. 4. Hos. 8. 4. Amos 3. 2. He approveth, loveth, and delighteth in them, and in the course of their lives, and therefore will recompence them: Or, he careth for and directeth their actions to a blessed Issue.

All their wicked designs and courses shall come to nothing, and they shall perish with them.
