Isaiah 66:4 - Exposition

Their delusions ; or, their childish follies ( LXX ; ἐμπαίγματα ) . As God sends on some men "strong delusion that they should believe a lie" ( 2 Thessalonians 2:11 ), so on others he sends a spirit of childish folly, which makes their conduct silly and headstrong. Persons whose characters are of this stamp are especially liable to vain and groundless "fears." When I called, none did answer (comp. Isaiah 65:12 , and see the comment on that passage).
