What does Psalm chapter 78 mean?
Asaph's psalms often start with expressions of deep resentment (Psalm 73:2–3; 74:1; 77:2–3; 79:5) which are overcome by reassurance about God's nature (Psalm 73:16–18; 74:12; 77:10–11; 79:13). This psalm is a resource which encourages that very process. This makes the use of the term maskiyl appropriate. Maskiyl is used for thoughtful, reflective psalms (Psalm 32; 52; 89).Israel was always meant to remember what God had done for them (Exodus 10:2). These stories were passed from generation to generation (Psalm 44:1). Asaph commits to teaching his era's children about all the Lord's incredible work on behalf of Israel. This is both an encouragement to trust God and a warning about those who failed to honor Him (Psalm 78:1–8).
An example of failure is the Ephraimites. No context is given for the remark about them losing heart and turning away from God. Some interpreters believe this is a prophetic comment. Others suggest it symbolizes some spiritual failure which led to Judah, not Ephraim, becoming dominant over the twelve tribes. Still another view is that this refers to a literal event which is not recorded elsewhere in the Bible (Psalm 78:9–11).
The most spectacular examples of the Lord's power and love for Israel came during the exodus from Egypt. God brought intense plagues on Egypt, breaking the nation's power and showing the Lord's supremacy (Exodus 3:19–20; 6:6–8; 7:15). This led to the parting of the Red Sea (Exodus 14:21–22), which sealed Israel's rescue from slavery. God's power was evident day and night (Exodus 13:21–22). He even provided plentiful fresh water in a desert wilderness (Exodus 15:23–25). But Israel continued to complain, even as God miraculously provided food and water. Rather than gratitude for earlier miracles, the people became entitled and doubtful (Psalm 78:12–20).
God responded to Israel's disrespect and arrogance with a display of fiery power (Numbers 11:1–3). Then, mercifully, He provided food in the form of bread and meat (Exodus 16:12–15). Even then, the people were not satisfied, so God struck them (Numbers 11:33) with a plague (Psalm 78:21–31).
This pattern of forgetfulness and complaining continued for Israel's entire journey through the wilderness and into their settlement in Canaan. No matter how often the Lord intervened, the people fell back into disobedience. Rather than destroying them outright, God chose to be merciful. This patience is amazing, considering all the intense disasters which God brought onto the people of Egypt (Exodus 3:20). Asaph describes the ten plagues (Exodus 7—12); this included the death of Egypt's firstborn (Exodus 12:29–30) and the first Passover (Exodus 12:12–14). Then God brought His people safely across the Red Sea, drowning their enemies (Exodus 14:26–29). He then empowered the people to overcome depraved Canaanite nations to settle in the Promised Land (Psalm 78:32–55).
After entering Canaan, Israel continued to fall into sin and rejection of their Lord God (Judges 2:16–19). As promised (Deuteronomy 11:26–28), God responded by allowing other nations to oppress and even conquer Israel (Deuteronomy 28:15–25). Among the most embarrassing of these defeats was a battlefield loss to the Philistines (1 Samuel 4:10), who temporarily captured the ark of the covenant (1 Samuel 4:11). Some of Israel's leading priests were killed in that event (Psalm 78:56–64).
Through all these events, the Lord was still working for Israel's benefit. The lessons and experiences in Sinai and Canaan led to the rise of David (1 Samuel 16:1–13; 2 Samuel 1:4). He established his capital on mount Zion, which became the city of Jerusalem. Though David was not Israel's first king (1 Samuel 10:21–24), he was its greatest ruler (Psalm 78:65–72).
These highlights cover Israel's history from slavery in Egypt to a kingdom under the rule of David. Asaph's purpose is to support the idea that no matter how far Israel fell, God was still with them. He has always rewarded those who are faithful to Him.
