The angels of peace weep bitterly, the highways are wasted
     (Isa. 33:7, 8).

     The work of righteousness shall be peace; and My people
     shall dwell in a habitation of peace (Isa. 32:17, 18).

[2] That it is Divine and heavenly peace that is meant in the Word by “peace” can be seen also from other passages where it is mentioned (As Isa. 52:7; 54:10; 59:8; Jer. 16:5; 25:37; 29:11; Hag. 2:9; Zech. 8:12; Psalm 37:37; and elsewhere.) Because “peace” means the Lord and heaven, and also heavenly joy and the delight of good, “Peace be with you” was an ancient form of salutation that is still in use; and it was ratified by the Lord in His saying to the disciples whom He sent forth: 

     Into whatsoever house ye enter, first say, Peace be to
     this house; and if a son of peace be there, your peace
     shall rest upon it (Luke 10:5, 6).

And when the Lord Himself appeared to the apostles, He said

     Peace be with you (John 20:19, 21, 26).

[3] A state of peace is also meant in the Word where it is said that: 

     Jehovah smelled an odor of rest (as Exod. 29:18, 25, 41;
     Lev. 1:9, 13, 17; 2:2, 9; 6:8, 14; 23:12, 13, 18; Num,
     15:3, 7, 13; 28:6, 8, 13; 29:2, 6, 8, 13, 36).

“Odor of rest” in the heavenly sense signifies a perception of peace.{1} As peace signifies the union of the Divine Itself and the Divine Human in the Lord, also the conjunction of the Lord with heaven and with the church, and with all who are in heaven, and with all in the church who receive Him, so the Sabbath was instituted as a reminder of these things, its name meaning rest or peace, and was the most holy representative of the church.  For the same reason the Lord called Himself “the Lord of the Sabbath” (Matt. 12:8; Mark 2:27, 28; Luke 6:5).{2}

{Footnote 1} In the word an “odor” signifies the perception of agreeableness or disagreeableness, according to the quality of the love and faith of which it is predicated (n. 3577, 4626, 4628, 4748, 5621, 10292).  An “odor of rest,” in reference to Jehovah, means a perception of peace (n. 925, 10054).  This is why frankincense, incense, and odors in oils and ointments, became representative (n. 925, 4748, 5621, 10177).

{Footnote 2} The “Sabbath” signifies in the highest sense the union of the Divine Itself and the Divine Human in the Lord; in the internal sense the conjunction of the Divine Human of the Lord with heaven and with the church; in general, the conjunction of good and truth, thus the heavenly marriage (n. 8495, 10356, 10730).  Therefore “rest on the Sabbath day” signified the state of that union, because then the Lord had rest, and thereby there is peace and salvation in the heavens and on the earth; and in a relative sense it signified the conjunction of the Lord with man, because man then has peace and salvation (n. 8494, 8510, 10360, 10367, 10370, 10374, 10668, 10730).
