Exodus 10:27

10:27 But the Lord hardened Pharaoh’s heart, and he was not willing to release them.

Exodus 19:23

19:23 Moses said to the Lord, “The people are not able to come up to Mount Sinai, because you solemnly warned us, ‘Set boundaries for the mountain and set it apart.’”

tn The construction is emphatic: “because you – you solemnly warned us.” Moses’ response to God is to ask how they would break through when God had already charged them not to. God knew them better than Moses did.

tn Heb “sanctify it.”
