8477. 'And Moses said to them' means an admonition. This is clear from the meaning of 'saying', which includes what comes after it, in this instance an admonition that they should not leave any of it till the morning, for 'saying' may also mean admonishing, see 7090, 8178

Truly spiritual peace becomes part of our being when we develop other spiritual practices such as trust in the Lord, love towards other people and an understanding that individually we are part of a greater design. Such things bring us peace which Swedenborg says is at the very heart of heaven and along with innocence, makes heaven. See Heaven and Hell 288 where we read, “Innocence and peace walk hand in hand.”

And for a wonderful description of peace, how we get it and what it really means read all of Apocalypse Revealed 306. Just a small part of it says, “Peace symbolizes everything whatever that comes from the Lord, and so everything pertaining to heaven and the church, and the blessings of life in them….
It follows from this that peace means charity, spiritual security, and inner rest, for when a person abides in the Lord, he is at peace with his neighbor, which is a state of charity, and he has protection from hell, which is spiritual security. And when he is at peace with his neighbor and has protection from hell, he enjoys an inner rest from evils and falsities.”

Following this are many quotes from the Word where peace is mentioned and here are just two of them.
“...unto us a Child is born, unto us a Son is given; the government will be upon His shoulder. His name will be called... God, Hero, Everlasting Father, Prince of Peace. Of the increase of His government and peace there will be no end... (Isaiah 9:6-7)

(Jesus said,) "Peace I leave with you, My peace I give to you." (John 14:27)
