'Appear Before Me' in the Bible

Pharaoh said to him, "Go from me! Watch out for yourself! Do not appear before me again, for when you see my face you will die!"

Thou shalt keep the feast of unleavened bread: (thou shalt eat unleavened bread seven days, as I commanded thee, in the time appointed of the month Abib; for in it thou camest out from Egypt: and none shall appear before me empty:)

But the firstling of an ass thou shalt redeem with a lamb: and if thou redeem him not, then shalt thou break his neck. All the firstborn of thy sons thou shalt redeem. And none shall appear before me empty.

David replied, “Good, I will make a covenant with you. However, there’s one thing I require of you: Do not appear before me unless you bring Saul’s daughter Michal here when you come to see me.”

When ye come to appear before me, who hath required this at your hand, to tread my courts?
