New Defender's Study Bible Notes
29:18 vision. The word “vision” here does not refer to far-sighted imagination, as this verse is commonly applied, but rather to actual divine revelation.
29:18 perish. This word, “perish,” means “open” or “exposed.” That is, when people today reject or ignore the revealed Word of God, they are open and helpless to resist the humanistic and occultic doctrines of men and devils.
29:18 happy. True happiness, or blessing, is found only through “keeping”—that is, “guarding” God’s Word, then obeying and proclaiming it.
