Here's an extract from Swedenborg's explanation of the inner meaning of the Book of Revelation, in which he has collected a nice set of passages from the Word, about peace. It's powerful to read them as a set.

This is from Apocalypse Revealed 306:

"[In the Word,] 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. In the highest or inmost sense, these are blessings of peace.

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.

Accordingly, since all these blessings come from the Lord, it can be seen what is symbolically meant by peace in general and in particular in the following passages:

...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)

(Jesus said,) "These things I have spoken to you, that in Me you may have peace." (John 16:33)

In His days the righteous shall flourish, and much peace... (Psalms 72:3, 7)

Then I will make a covenant of peace... (Ezekiel 34:25, 27; 37:25-26)

How delightful upon the mountains are the feet of him who brings good news, who proclaims peace..., who says to Zion, "Your King reigns!" (Isaiah 52:7)

Jehovah bless you and... lift up His countenance upon you, and give you peace. (Numbers 6:24-26)

Jehovah will bless His people with peace. (Psalms 29:11)

(Jehovah) will redeem my soul in peace... (Psalms 55:18)

The work of (Jehovah) is peace, [and] the labor of righteousness, rest and security forever, that (they) may dwell in a tabernacle of peace, in secure tents, and in tranquil places of rest. (Isaiah 32:17-18)

(Jesus said to the seventy that He sent out,) "Whatever house you enter, first say, 'Peace to this house.' And if a son of peace is there, your peace will rest on it." (Luke 10:5-6, cf. Matthew 10:12-14)

The wretched shall possess the earth, and shall delight themselves in an abundance of peace... ...observe the upright man, for the final state for that man is peace. (Psalms 37:11, 37)

(Zacharias, prophesying, said,) ."..the Dayspring from on high has appeared..., to guide our feet into the way of peace." (Luke 1:78-79)

Depart from evil and do good; seek peace and pursue it. (Psalms 34:14)

Much peace have those who love Your law... (Psalms 119:165)

"Oh, that you had heeded My commandments! Then your peace would have been like a river...." "There is no peace," says Jehovah, "for the impious." (Isaiah 48:18, 22)

(Jehovah) will speak peace to His people... Righteousness and peace will kiss. (Psalms 85:8, 10)

There is no peace in my bones because of my sin. (Psalms 38:3)

He has filled me with bitterness... ...moved (is) my soul far from peace; I have forgotten goodness. (Lamentations 3:15, 17)

And so on in many other places, from which it can be seen that the aforesaid blessings are meant by peace. Fix your mind on spiritual peace, and you will clearly see.

So likewise in the following places: Isaiah 26:12; 53:5; 54:10, 13; Jeremiah 33:6, 9; Haggai 2:9; Zechariah 8:16, 19; Psalms 4:6-8; 120:6-7; 122:6-9; 128:5-6; 147:14."
