(Genesis 42:29.) The things which befall are the things which were of providence, or which were provided, because everything which befalls, or happens, in other words what is called fortuitous, and is ascribed to chance, or to fortune, is of providence. (Arcana Coelestia 5508)

366. Standing before the throne and before the Lamb. This symbolically means, listening to the Lord and doing what He commands.

To stand before the Lord means, symbolically, to hear and do what He commands, like one who stands before a king.

This is also the symbolic meaning of standing before God, or in the presence of God, elsewhere in the Word, as when the angel said to Zacharias,

I am Gabriel, who stands in the presence of God... (Luke 1:19)

A man who stands before Me shall not be cut off forever. (Jeremiah 35:19)

These are the two offspring of the olive tree, who stand before the Lord of the whole earth. (Zechariah 4:14)

(He) separated the tribe of Levi... to stand before Jehovah... (Deuteronomy 10:8)

And so on elsewhere.
