As the plagues came on Pharaoh and the Egyptians, he began to weaken a little bit.

Pharaoh said to Moses, "Go, sacrifice to your God [here] in the land [of Egypt]. And Moses said, It is not suitable or right to do that; for the animals the Egyptians hold sacred and will not permit to be slain, are those which we are accustomed to sacrifice to the Lord our God; if we did this before the eyes of the Egyptians, would they not stone us? We will go three days' journey into the wilderness and sacrifice to the Lord our God, as He will command us" (Ex. 8:25-27, Amplified).

This was Pharaoh's first offer, but Moses was bold in faith and refused to compromise. Moses spoke for God and completely refused anything less than what God demanded.

Moses even exposed Pharaoh's false religion as he mentioned that the Egyptians held certain animals to be sacred. Moses made it clear that his firm intention was to obey God completely.

That Moses' faith was becoming bolder and bolder is also seen in that he prayed for an end to the plague of flies. This was not presumption on Moses' part because he already had assurance from God that such a prayer was in accordance with His will.

"Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man" (Eccles. 12:13).
