John Wesley on Isaiah 8:4

To cry - To speak and to know his parents; which is within the space of two years. And his agrees with the other prophecy, chap.7:16. Before the child shall know to refuse the evil and chuse the good, which requires a longer time than to distinguish his parents, and suits well to Shear - Jashub, who, being born some years before, was capable of that farther degree of knowledge, as soon as this was capable of the lower degree. Before - In his presence, and by himself and his forces.
