Did God Ask Moses to Lie?

Did God ask Moses to tell a lie when He asked Moses to ask the Pharaoh for a three-day journey into the wilderness to offer sacrifices to God?

"The elders of Israel will listen to you. Then you and the elders are to go to the king of Egypt and say to him, 'The LORD, the God of the Hebrews, has met with us. Let us take a three-day journey into the wilderness to offer sacrifices to the LORD our God.' (Exodus 3:18 NIV)

God did not ask Moses to lie. If the Pharaoh had accepted the request, it would be so. But the Pharaoh had not accepted the request. Finally after the ten plagues, the Pharaoh expelled the Israelites from his land.

During the night Pharaoh summoned Moses and Aaron and said, "Up! Leave my people, you and the Israelites! Go, worship the LORD as you have requested. (Exodus 12:31 NIV)

After that, the Pharaoh regretted his action and decided to pursued the Israelites.

When the king of Egypt was told that the people had fled, Pharaoh and his officials changed their minds about them and said, "What have we done? We have let the Israelites go and have lost their services!" (Exodus 14:5 NIV)

God had foretold to Moses that the Pharaoh will expel them.

So I will stretch out my hand and strike the Egyptians with all the wonders that I will perform among them. After that, he will let you go. (Exodus 3:20 NIV)

Then the LORD said to Moses, "Now you will see what I will do to Pharaoh: Because of my mighty hand he will let them go; because of my mighty hand he will drive them out of his country." (Exodus 6:1 NIV)

Now the LORD had said to Moses, "I will bring one more plague on Pharaoh and on Egypt. After that, he will let you go from here, and when he does, he will drive you out completely. (Exodus 11:1 NIV)

In the same manner, the LORD hardened the hearts the enemies of Israel during the time of Joshua so that they could be destroyed completely.

So Joshua took this entire land: the hill country, all the Negev, the whole region of Goshen, the western foothills, the Arabah and the mountains of Israel with their foothills, from Mount Halak, which rises toward Seir, to Baal Gad in the Valley of Lebanon below Mount Hermon. He captured all their kings and put them to death. Joshua waged war against all these kings for a long time. Except for the Hivites living in Gibeon, not one city made a treaty of peace with the Israelites, who took them all in battle. For it was the LORD himself who hardened their hearts to wage war against Israel, so that he might destroy them totally, exterminating them without mercy, as the LORD had commanded Moses. (Joshua 11:16-20 NIV)

The LORD is treating the Palestinians the same way. When offered up to 50% of the land in 1948, the Palestinians refused the offer. As they continued to fight, the land offered got smaller and smaller.
