Charles Spurgeon Commentary Isaiah 7:14-15

"Therefore the Lord himself will give you a sign: behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel. Butter and honey shall he eat, when he knoweth to refuse the evil, and choose the good." — Isaiah 7:14-15 (ASV)

And shall call his name Immanuel. Butter and honey shall he eat, that he may know to refuse the evil, and choose the good.

Therefore, a wise commentator says that, before children are able to learn, their parents should regard their very feeding as a means for them to learn the difference between good and evil.
