8th Grade Bible & Scripture — Old Testament Survey — God's Covenant Story
God Delivers His People and Establishes His Covenant at Sinai
After Joseph's death, a new pharaoh arose who 'did not know Joseph' (Exodus 1:8). The Israelites, who had grown into a large population in Egypt, were enslaved and brutally oppressed for approximately 400 years. Pharaoh even ordered the murder of all newborn Hebrew boys in an attempt to control the population.
But God had not forgotten His covenant with Abraham. He raised up Moses — a Hebrew child miraculously preserved and raised in Pharaoh's own household — to be the deliverer of His people. When God appeared to Moses in the burning bush, He revealed His covenant name: Yahweh (I AM WHO I AM), signifying that He is the self-existent, eternal, and unchanging God who keeps His promises.
Through ten devastating plagues, God demonstrated His absolute sovereignty over Egypt and all its gods. Each plague directly challenged a specific Egyptian deity, showing that Yahweh alone is the true God. The final plague — the death of the firstborn — was the most terrible, and it introduced the Passover.
On the night of the Passover, each Israelite family sacrificed a lamb and applied its blood to the doorposts of their home. When the angel of death passed through Egypt, he 'passed over' every home marked by the blood. This event is the most important Old Testament foreshadowing of Christ's sacrifice — the Apostle Paul would later write, 'Christ, our Passover lamb, has been sacrificed' (1 Corinthians 5:7).
God then led His people through the Red Sea on dry ground, destroying Pharaoh's pursuing army. The Exodus became the defining event of Israel's national identity — the act by which God redeemed His people from slavery and made them His own.
At Mount Sinai, God entered into a covenant with the nation of Israel. Unlike the Abrahamic Covenant, the Mosaic Covenant was conditional: 'If you obey me fully and keep my covenant, then out of all nations you will be my treasured possession' (Exodus 19:5). Blessings would follow obedience, and curses would follow disobedience.
The heart of this covenant was the Ten Commandments (Exodus 20), which reveal God's moral character and His standards for human conduct. The first four commandments address our relationship with God (no other gods, no idols, do not misuse God's name, keep the Sabbath), and the last six address our relationships with other people (honor parents, do not murder, commit adultery, steal, bear false witness, or covet).
The law was never intended as a means of earning salvation — Israel was already saved by grace through the Exodus before receiving the law. Rather, the law revealed God's holy character, exposed human sinfulness, and pointed to the need for a Savior who could perfectly fulfill what no human could.
God instructed Moses to build the Tabernacle — a portable sanctuary where God's presence would dwell among the Israelites during their wilderness journey. Every detail of the Tabernacle was prescribed by God and carried deep symbolic meaning.
The sacrificial system established at the Tabernacle taught Israel that sin requires a blood atonement — the death of an innocent substitute in place of the guilty sinner. 'Without the shedding of blood there is no forgiveness' (Hebrews 9:22). The entire sacrificial system pointed forward to Christ, the ultimate and final sacrifice who would take away the sin of the world.
The Tabernacle itself foreshadowed the incarnation of Christ. Just as God 'tabernacled' among Israel in the wilderness, the Gospel of John declares that 'the Word became flesh and made his dwelling [literally, tabernacled] among us' (John 1:14).
Write thoughtful responses to the following questions. Use evidence from the lesson text, Scripture references, and primary sources to support your answers.
How does the Passover lamb in Exodus 12 foreshadow the sacrifice of Jesus Christ? List at least four parallels between the Passover and the crucifixion.
Guidance: Consider: the lamb must be without blemish, its blood must be applied, it brings deliverance from death, and its bones are not broken. Compare with John 1:29, 1 Corinthians 5:7, and John 19:36.
Why does God give the Ten Commandments after delivering Israel from Egypt, not before? What does this order teach us about the relationship between grace and obedience?
Guidance: Think about the pattern: God saves first, then gives His law. Israel obeyed out of gratitude for redemption, not to earn it. How does this apply to Christians today?
What was the purpose of the sacrificial system at the Tabernacle? Why were animal sacrifices ultimately insufficient, and what did they point to?
Guidance: Consider Hebrews 10:1-4, which explains that animal sacrifices could never permanently remove sin but served as a shadow of the perfect sacrifice to come in Christ.
