Matthew Poole and continuators on Isaiah 26:3

3 Thou wilt keep him in perfect peace, whose mind is staied on thee : because he trusteth in thee.

Heb. the fixed thought or mind (i. e. the Man whose Mind and Thoughts are fixed and setled upon thee by Faith, as the next Clause explains it, the Qualification being put for the Person so qualified, as folly and wisdom are put for a Fool and a Wise man, Prov. 24. 9. Mic. 6. 9. and peace for a Man of peace, Psal. 120. 7.) thou wilt keep in peace peace, i. e. in all manner of peace, in constant and perfect peace. In the foregoing Verse the Righteous were admitted into the City, and here they are preserved and defended in it by God's Almighty Power.

Marginal references: Heb. peace, peace.; Or, thought, [illegible: 1+ letters]r, imagination.
