For before the child shall know... — The words imply the age of approaching manhood, and predict the downfall of Pekah and Rezin, as the longer period of Isaiah 7:8 predicted the entire downfall and annihilation of one of the two kingdoms which they represented. The words “good and evil” are better taken of moral choice (Genesis 3:5; Deuteronomy 1:39) rather than (with some critics, who appeal to 2 Samuel 19:35) of the child’s discernment of food as pleasant or the reverse. (See Genesis 2:9; 1 Kings 3:9.)

The prediction was fulfilled in the siege of Samaria by Salmaneser, and its capture by Sargon (1 Kings 16:9; 1 Kings 17:6), a fulfilment all the more remarkable in that it was preceded by what seemed an almost decisive victory over Judah (2 Chronicles 28:5-15), of which the prophet makes no mention.
