What does Exodus 7:4 mean?
God is reassuring Moses (Exodus 6:1–6) that everything is happening according to a divine plan (Exodus 3:19–20). Pharaoh rejected the initial request to free the Hebrew slaves (Exodus 5:6–9). He will continue to do so, first from his own obstinate attitude (Exodus 7:14; 8:15; 9:7), and later through God's example-making judgment (Exodus 9:12; 10:1; 14:8).This resistance is not a sign that the Lord's plan is being thwarted. Rather, it is part of the plan. God intends to send a clear message about His own power (Exodus 7:2–4). He also seeks to establish His unique relationship with the nation of Israel (Exodus 6:6–7). After ten devastating plagues, there will be no doubt that the Lord is supreme (Expodus 7:5), and that His people were freed entirely by His power (Exodus 12:41).
Despite advanced age (Exodus 7:7), Moses and Aaron will faithfully continue to obey the Lord's instructions (Exodus 7:6).
