Heb. The fixed thought or mind (i.e. the man whose mind and thoughts are fixed and settled upon thee by faith as the next clause explains it, the qualifications being put for the person so qualified, as folly and wisdom are put for a fool and a wise man, Pro_24:9Mic_6:9, and peace for a man of peace, Psa_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 were preserved and defended in it by God’s almighty power.
