Isaiah 28:9

Whom shall he teach knowledge? and whom shall he make to understand doctrine? them that are weaned from the milk, and drawn from the breasts.

Isaiah 28:9 (KJV)

Context

Isaiah 28:9 sits within a prophecy of rebuke against the leaders of Israel, who are charged with drunkenness and moral corruption. They have rejected God’s warnings and His prophets, so Isaiah confronts their arrogance and spiritual blindness. The verse is a rhetorical question that exposes their true condition: though they consider themselves mature, they are like infants who cannot receive solid teaching.

Meaning

The question “Whom shall he teach knowledge?” points to God as the source of all true knowledge. The “he” is God Himself, who alone can give understanding. The verse then asks, “and whom shall he make to understand doctrine?” Doctrine here means the teachings and truths of God’s Word. The answer is “them that are weaned from the milk, and drawn from the breasts.” This imagery describes those who have moved beyond spiritual infancy, ready for deeper truths rather than basic milk.

The people of Isaiah’s day mocked the prophet’s message, treating it as fit only for children. Yet their mockery revealed their own immaturity. They were not weaned; they were still like unweaned infants, unable to digest the word of the Lord. Because they rejected God’s patient instruction, judgment would come through foreign invaders speaking an unintelligible language, as the following verses show.

Biblical connections

This verse connects with the broader biblical theme that God reveals truth to the humble and receptive, while the proud remain ignorant. The contrast between milk and solid food appears elsewhere in Scripture, such as in Hebrews 5:12-14, where believers are urged to move from elementary teachings to maturity. Here, Isaiah uses the same contrast to call God’s people to a teachable spirit.

Application

Isaiah 28:9 challenges believers to examine their own receptivity to God’s teaching. Spiritual maturity is not about age or position but about a humble, willing heart. God imparts knowledge and understanding to those who have moved beyond the basics and are ready for deeper truths. This calls for a deliberate pursuit of growth in the Word, so that we can discern truth from error and live according to God’s will.

• God is the ultimate teacher of knowledge and understanding.

• He gives wisdom to those who are ready and receptive, having grown beyond spiritual infancy.

• Believers are encouraged to pursue maturity, growing in knowledge and understanding of God’s Word.

Reflection

Consider whether you are still clinging to the milk of basic teaching or are ready for the solid food of deeper doctrine. Ask God to give you a teachable spirit, one that is humble and eager to learn from Him. True understanding comes not from pride but from a heart that is weaned from self-sufficiency and drawn to God’s instruction.
