Why did Pharaoh act this way? The memory of Joseph's service had faded.
Pharaoh's fear of the Israelites is amplified by a deliberate turning away from the past. The text mentions, "Now there arose a new king over Egypt, which knew not Joseph" (v. 8). This isn't just a chronological marker; it's theological.
Joseph had saved Egypt from famine, a profound act of service that secured a place for his family. Yet, this new king, unburdened by gratitude or loyalty, sees only a potential threat. The benefits Joseph provided are forgotten, leaving no room for empathy or a fair assessment of the Israelites' presence.
This highlights a common human tendency: when we forget past mercies and the good done for us, we become more susceptible to suspicion, prejudice, and injustice. The absence of gratitude paves the way for cruelty.
