'Let Us' in the Bible

"The elders of Israel will listen to you, and then you and they are to go to the king of Egypt and say to him, "The LORD God of the Hebrews has met with us. Now, let us take a three-day journey into the desert to sacrifice to the LORD our God.'

Then they said, "The God of the Hebrews has met with us. Please let us go a three-day journey into the desert to offer sacrifices to the LORD our God so he does not strike us with pestilence or sword."

Moses said, "You must let us havesacrifices and burnt offerings to offer to the LORD our God.

And when Pharaoh stubbornly refused to let us go, the LORD killed every firstborn in the land of Egypt, from the firstborn of humans to the firstborn of animals. Therefore, I sacrifice to the LORD every male that first opens the womb, but I redeem every firstborn of my sons.

Is this not what we told you in Egypt, when we said, "Leave us alone!' and "Let us serve the Egyptians!'? Indeed, it would have been better for us to serve the Egyptians than to die in the desert!"
