v1-5: Moses and Aaron's first meeting with Pharaoh.
v1: Their message and authority from God, the God of Israel. God recognised His people, see 3.10.
v2: Pharaoh had no respect for God, "Who is the Lord?" Contrast 1 Cor 3.11, "Who am I?" Since Pharaoh did not know God, he did not obey Him; disobedience is a mark of unbelief. In contrast, the believer is characterised by obedience.
v3: The request repeated and extended, that the Lord had commanded His people to offer sacrifices to Him. The Lord is the God of the Hebrews; He chose this people as His own special people.
This was the first of repeated requests to Pharaoh, each time refused; 7.10, refused 7.13; 7.15-18, refused 7.22-23; 8.1-4, refused 8.15,19; 8.20-23, refused 8.32; 9.1-4, refused 9.7,12; 9.13-19, refused 9.34-35; 10.1-6, refused 10.11,20.27.
v4-5: Pharaoh responded by accusing the children of Israel of idleness.
v6-9: Pharaoh increased the people's work load, by insisting they find their own straw for making bricks, but not diminishing the quantity of bricks required. So Moses' first request was refused; when the Lord works, circumstances can become worse. Yet God's promises had not failed.
v10-13: Pharaoh's command was passed to the slaves.
v14: Not surprisingly, the children of Israel could not fulfil the target set, so their foremen, or officers, were beaten.
v15-16: The foremen grumbled about the treatment they had received.
v17: Pharaoh's response repeated his accusation of laziness. By referring to their request to go to sacrifice to the Lord God, Pharaoh set them against Moses and Aaron.
v18-19: The command was repeated, that the number of bricks had to be maintained.
v20-21: The foremen went to Moses and Aaron, whom they now blamed for their suffering. This was the first attack on the leadership of Moses and Aaron, a problem that recurred for many years. We must expect difficulties when we serve the Lord.
Note too that Pharaoh effectively created division amongst the Israelites.
v22-23: Moses did not stay to argue with the leaders of the children of Israel; instead he took his problem to the Lord. He did not understand why such things should have happened. See also Acts 7.25 about Moses' struggle earlier. Wherever the problem is, whether in ourselves or in others, we must turn to the Lord for His answers.
