Charles H. Spurgeon on Psalms 1:1

"Walketh NOT....NOR standeth....NOR sitteth," etc. Negative precepts are in some cases more absolute and peremptory than affirmatives; for to say, "that hath walketh in the counsel of the godly," might not be sufficient; for, he might walk in the counsel of the godly, and yet walk in the counsel of the ungodly too; not both indeed at once, but both at several times; where now, this negative clears him at all times. Sir Richard Baker.
