Isaiah 7:21 (KJV) says: "And it shall come to pass in that day, that a man shall nourish a young cow, and two sheep."

The book of Isaiah is a powerful and prophetic book in the Old Testament, written by the prophet Isaiah during a time of great political and social upheaval in the nation of Judah. The book is divided into two main parts - chapters 1-39, which focus more on judgment and the consequences of sin, and chapters 40-66, which speak of hope, restoration, and the coming of the Messiah.

In this particular verse, Isaiah is speaking about an apocalyptic future where there will be a scarcity of food and resources. The image of a man nourishing a young cow and two sheep is quite significant. It speaks to the desperate measures people will have to resort to in order to survive in those difficult times. Cows and sheep were valuable assets in ancient agricultural societies, providing milk, wool, and meat. To be reduced to a single cow and two sheep demonstrates the extreme scarcity and poverty that will prevail in that future day.

In the context of the book of Isaiah, this verse is a part of a larger section in which the prophet is warning the people of Judah about the impending judgment of God. The king of Judah at that time, King Ahaz, was facing military threats from neighboring nations and was tempted to seek help from Assyria rather than relying on God. In response to this, Isaiah delivers a message from God, urging Ahaz to have faith and trust in God's promise of deliverance.

The verse is part of a vivid portrayal of the dire consequences of abandoning God and seeking worldly solutions. It serves as a warning to the people of Judah to turn back to God and to trust in His provision, rather than relying on their own strength or the help of foreign nations.

Symbolically, the man nourishing a young cow and two sheep also represents the care and nurturing of the remnants of God's people. Despite the scarcity and hardship, there is still a remnant that will be sustained and cared for by God. This image of the man tending to the few remaining animals serves as a symbol of God's ongoing care and provision for His faithful, even in the midst of chaos and scarcity.

The themes of trust, faith, and the consequences of sin are central to this verse. It serves as a powerful reminder of the importance of relying on God and His provision, rather than seeking worldly solutions or placing our trust in human strength. It also speaks to the consequences of sin and the need for repentance and turning back to God in times of trouble.

In a broader sense, this verse can also be seen as a foreshadowing of the ultimate deliverance and provision that God provides through Jesus Christ. In the face of scarcity and desperation, God promises to sustain and care for His people, ultimately bringing restoration and hope through the coming of the Messiah.

Overall, Isaiah 7:21 is a powerful and evocative verse that speaks to the themes of trust, faith, and the consequences of sin. It serves as a warning to the people of Judah to turn back to God and trust in His provision, while also offering hope and assurance of God's ongoing care and sustenance for His faithful.
